The Calibre 9RB2 was unveiled at Watches & Wonders 2025, and let’s just say—it’s a total game-changer.

The SLGB001 is the first watch to feature the new Spring Drive Caliber 9RB2, introduced in Grand Seiko’s Evolution 9 Collection. This innovative movement offers an accuracy of ±20 seconds per year, setting a new benchmark for precision in mainspring-driven watches. The watch has a 37mm Platinum 950 case, combining elegance with durability. Its dial, inspired by the frost-covered trees of Japan’s Kirigamine Highlands, showcases a unique “Ice Forest” texture.

Much like the Limited Edition above, the SLGB003 pays homage to the stunning Ice Forests of the Kirigamine Highlands in Japan’s Shinshu region. While the SLGB001’s dial features a more intense blue, the SLGB003 opts for a subtler approach with delicate pale blue accents that capture the essence of the frosty landscape. The dial’s silver-tinged blue hue perfectly mirrors the serene, frosty atmosphere of the Kirigamine Highlands, where the winter air gives the trees their beautiful icy coating.

The SLGB003 replaces the leather strap of the SLGB001 with a high-intensity titanium bracelet that combines durability with lightweight comfort. It also features a new three-step micro-adjustment clasp that doesn’t require tools, allowing for 2mm adjustments to ensure a perfect fit and ultimate comfort throughout the day.

This is also scheduled for release in June 2025 and will be available at Grand Seiko Boutiques and select retailers worldwide. With a price tag of $10,900, it combines the precision of the Spring Drive Calibre 9RB2 with a refined design, making it a standout addition to any collection.

A stunning addition to the Heritage Collection, this timepiece celebrates elegance and nature. The soft lilac dial, inspired by the kiri (paulownia) flower—known as the “empress tree” and “princess tree”—captures the delicate beauty of this feminine bloom, which also serves as Iwate Prefecture’s symbol. Boasting a pressed pattern that represents Mt. Iwate as seen from Shizukuishi, it is a graceful nod to the region’s natural beauty.

Powered by the manual-winding Caliber 9S64, which features a 72-hour power reserve, this watch delivers precision and reliability. The 36.5mm stainless steel case, along with the comfortable bracelet, ensures both style and practicality.

Inspired by the snowy landscape of Mt. Iwate during winter, this mechanical chronograph combines the beauty of deep snow with rugged mountain ridges. The dial showcases a striking dual-layered ‘Snow Blue’ hue, featuring an embossed pattern that mirrors the ridge lines of the mountain, providing breathtaking visual depth.

The connection between the watch and Iwate Prefecture is strong, as it is home to Grand Seiko’s GS Studio Shizukuishi, nestled within a tranquil forest.

Iwate, which, despite its challenging nature, teaches that “Even if life is rough, we should live with determination.”

The last of Grand Seiko’s collection at Watches & Wonders 2025 is the Tokyo Lion Tentagraph SLGC009, a bold and adventurous timepiece designed to “invite its owner on an adventurous journey.” This model features the Tentagraph Calibre 9SC5, a high-beat mechanical chronograph movement operating at 36,000 vibrations per hour with a 72-hour power reserve.

IWC Unveils Five New Ingenieur Watches at Watches and Wonders 2025

At Watches and Wonders 2025, IWC didn’t just show up—they brought the engineering heat. The brand’s iconic Ingenieur collection has returned with five fresh models that blend bold design with serious mechanical muscle. Originally penned by the legendary Gérald Genta, the Ingenieur has always stood out as a symbol of technical precision, and this year’s drop proves that legacy is alive, well, and back in the spotlight.

With revamped proportions, upgraded materials, and a design language that honours the past while propelling towards the future, IWC Schaffhausen’s new Ingenieur lineup emphasizes balance between form and function, performance and polish. It represents a comeback that feels meticulously planned rather than hurried. And with Brad Pitt making headlines for his upcoming Formula 1 film—where IWC also has a role—it’s clear the brand is performing at its best on-screen and off.

Ingenieur Automatic 40 – 18 Caret 5N Gold

  • Brand: IWC Schaffhausen
  • Model: Ingenieur Automatic 40 – 18 Caret 5N Gold
  • Reference: IW328702
  • Diameter: 40 mm
  • Thickness: 10.4 mm
  • Material: Titanium
  • Dial Colour: Black Dial
  • Calibre: 32111 Calibre
  • Power Reserve: 120 Hours
  • Water Resistance: 10 Bar ( 100 metres, 330 feet )
  • Price: USD $46,600

Let’s kick things off with a heavyweight—the Ingenieur Automatic 40 in 18K 5N gold. This is IWC at its boldest, taking Genta’s iconic design blueprint and enveloping it in a warm, radiant case that doesn’t whisper luxury—it speaks it fluently. With its 40mm integrated case and bracelet crafted entirely from solid gold, this watch isn’t just about time—it’s about presence.

The black grid-pattern dial adds subtle texture and depth, preventing the rich gold tones from feeling overpowering. Gold appliques and hands elevate the look, while the in-house Calibre 32111 movement beneath delivers real power—providing a 120-hour power reserve. With 100 meters of water resistance, you’ve got a timepiece that’s as capable as it is commanding.

It’s a rare balance of high-end craftsmanship and daily practicality. The combination of brushed and polished surfaces interacts beautifully with the light, providing the watch with a dynamic, refined presence without ever veering into flashy territory.

Ingenieur Automatic 42 in Black Ceramic

  • Brand: IWC Schaffhausen
  • Model: Ingenieur Automatic 42 in Black Ceramic
  • Reference: IW338903
  • Diameter: 42 mm
  • Thickness: 11.5 mm
  • Material: Black Ceramic
  • Dial Colour: Black Dial
  • Calibre: 82110 Calibre
  • Power Reserve: 60 Hours
  • Water Resistance: 10 Bar ( 100 metres, 330 feet )
  • Price: USD $19,500

If the 18K gold Ingenieur is the wrist equivalent of red carpet energy, the Black Ceramic version is its polar opposite—and that’s exactly why it works. There’s no shine, no dazzle, no attention-seeking; just smooth, matte surfaces and a design that quietly asserts itself without saying a word. It’s the kind of watch that feels right at home in a high-tech control room or worn under a cuff by someone who prefers their luxury low-key.

What strikes you first isn’t the look—it’s the vibe. This watch has presence, but not in the traditional sense. It doesn’t shout. It doesn’t need to. The integrated design and monochromatic styling give it a futuristic edge, while the soft curves and sharp angles create a balance between sportiness and sophistication. It’s a bit more substantial than the 40mm counterparts, yet still manages to wear effortlessly.

You can tell it was built for people who value function as much as form. It’s tough, comfortable, and clearly designed to withstand wear without losing any of its character. While some watches try to impress with flash, this one earns respect through its design confidence and restraint. It’s almost as if the more you wear it, the more you understand it.

Honestly, this could be the sleeper hit of the entire Ingenieur release. It won’t appeal to everyone—and that’s the beauty of it. It’s perfect for someone looking for something a little different, a bit more modern, and a whole lot more stealth.

Ingenieur Perpetual Calendar 41

  • Brand: IWC Schaffhausen
  • Model: Ingenieur Perpetual Calendar 41
  • Reference: IW344903
  • Diameter: 41.6 mm
  • Thickness: 13.3 mm
  • Material: Stainless Steel
  • Dial Colour: Blue Dial
  • Calibre: 82600 Calibre
  • Power Reserve: 60 Hours
  • Water Resistance: 10 Bar ( 100 metres, 330 feet )
  • Price: USD $36,900

The Ingenieur Perpetual Calendar 41 is IWC’s boldest move yet in the revamped Ingenieur line. It’s not just a sport-luxury watch—it’s a mechanical statement. By merging Gérald Genta’s iconic design with Kurt Klaus’s legendary perpetual calendar module, IWC has created a piece that is both technically impressive and visually striking. The stainless steel case, measuring 41.6mm, houses a vibrant blue dial adorned with a grid pattern, giving it a modern yet timeless appeal.

What sets this watch apart is its ability to display the date, day, month, leap year, and moon phase—all adjusted via the crown. The subdials are thoughtfully arranged: the date at 3 o’clock, day and leap year at 9 o’clock, and month with moon phase at 6 o’clock. The moon phase display is so precise that it will deviate by only one day after 577.5 years. The IWC-manufactured Calibre 82600 is powering this complication, featuring a Pellaton winding system and a 60-hour power reserve. The movement is beautifully finished with circular graining, Geneva stripes, and blued screws, visible through the sapphire case back.

Despite its complexity, the watch maintains a sleek profile with a thickness of 13.3 mm and offers (100 metres, 330 feet) water resistance. The integrated H-link bracelet ensures comfort and provides a seamless look. The combination of brushed and polished surfaces on the case and bracelet adds depth and sophistication to the overall design.

In essence, the Ingenieur Perpetual Calendar 41 represents a harmonious blend of form and function. It pays homage to IWC’s rich heritage while embracing modern watchmaking advancements. This watch remains a compelling choice for those seeking a timepiece that embodies both technical prowess and elegant design.

IWC Schaffhausen Ingenieur Automatic 40 – Green Dial

Ingenieur Automatic 40 – Green Dial

  • Brand: IWC Schaffhausen
  • Model: Ingenieur Automatic 40
  • Reference: IW328908
  • Diameter: 40 mm
  • Thickness: 10.7 mm
  • Material: Stainless Steel
  • Dial Colour: Green Dial
  • Calibre: 32111 Calibre
  • Power Reserve: 120 Hours
  • Water Resistance: 10 Bar ( 100 metres, 330 feet )
  • Price: USD $12,900

This year, IWC gave the Ingenieur Automatic 40 a dose of adrenaline with a new Racing Green dial—a colour that’s as much about British racing heritage as it is about standing out without screaming. It’s a sporty, sophisticated look that wouldn’t feel out of place in a Formula 1 paddock, which makes sense considering IWC’s deepening connection to motorsport. With the brand’s presence trackside—and stars like Brad Pitt making waves in the F1 scene—it feels like the perfect moment for this kind of drop.

The 40mm stainless steel case is clean and purposeful, while the integrated bracelet adds that signature Genta flair. However, it’s the textured green dial that gives this model its character—subtle in the shade, punchy in the sun. Underneath, the in-house Calibre 32111 provides a serious 120-hour power reserve, and a soft-iron inner case safeguards the movement from magnetic fields. Additionally, there’s 100m of water resistance, making it capable of handling more than just good lighting and compliments.

For those who have been eyeing a modern luxury sport watch that performs well in both the paddock and the boardroom, this one hits the sweet spot. Its limitation to just 1,000 pieces adds to the appeal. With its motorsport DNA and the A-list energy surrounding IWC lately, this Racing Green Ingenieur is one of the more quietly confident releases of the year.

Ingenieur Automatic 35

  • Brand: IWC Schaffhausen
  • Model: Ingenieur Automatic 35
  • Reference: IW324901, IW324903, & IW324906
  • Diameter: 35 mm
  • Thickness: 9.4 mm
  • Material: Stainless Steel
  • Dial Colour: Silver Plated, Gold, & Black Dials
  • Calibre: 47110 Calibre
  • Power Reserve: 42 Hours
  • Water Resistance: 10 Bar ( 100 metres, 330 feet )
  • Price: USD $9,950 – $37,500,

IWC’s decision to scale down the Ingenieur to a 35mm case nods to timeless proportions and is a win for collectors who prefer their watches with a little more finesse. The design remains unmistakably Ingenieur—with that Genta-style squared case and integrated bracelet—but the smaller size offers refreshing wearability that feels just right on slimmer wrists or anyone looking for a more refined profile.

The lineup presents three dial options, each with its own unique character. There’s the Silver-Plated dial (Ref. IW324901), clean and versatile with a classic, everyday appeal. The Black version (Ref. IW324906) leans sporty and understated, perfect for someone seeking a go-to piece that never feels overdressed. Then, there’s the standout—18K 5N Gold with a matching gold dial (Ref. IW324903)—a warmer, more luxurious option that elevates the entire lineup into statement territory.

Inside, all three references are powered by the automatic Calibre 47110, offering a 42-hour power reserve that is visible through the sapphire caseback. At just 9.4mm thick and with 100m water resistance, it’s designed for comfortable wear all day, every day, with a level of polish suitable for everything from weekend denim to tailored evenings out.

For those who’ve always admired the Ingenieur but found the 40mm models a bit too bold, the 35mm range feels like IWC has achieved the right proportions—and the vibe. Pricing reflects the materials, with the silver and black dial steel models (IW324901 & IW324906) each retailing at USD $9,950, while the solid gold IW324903 commands a striking USD $37,500.
