2023 Synchron Poseidon Ice Diver Limited Edition 42mm

Here we have a 2023 Synchron Poseidon Ice Diver Limited Edition 42mm, a high-performance, cold-water tool watch born from an authentic professional collaboration with Swedish diving equipment giant Poseidon Dive Systems. Dating to March 2023, this exclusive reference belongs to a limited production series of only 1,000 pieces worldwide. Paying direct homage to iconic 1970s maritime heritage, this ultra-robust piece is legendary for its testing by the Swedish Armed Forces in sub-arctic conditions down to -30°C. The 42mm 316L surgical stainless steel case curves beautifully over the wrist with its unmistakable, retro cushion-shaped tonneau architecture. A remarkably compact lug-to-lug length of 45mm and a case thickness of 14mm give the watch an incredibly ergonomic, snug, and comfortable presence on the wrist despite its solid tool-watch dimensions. The case features clean satin-brushed surfaces, while a recessed, signed screw-down crown on the right side ensures uncompromising water resistance. Capping the case is a 37mm, 120-click unidirectional rotating dive bezel featuring a scratch-resistant sapphire crystal insert, precisely executed with standard 0-to-60 elapsed-time markings. A flat sapphire crystal with an advanced anti-reflective coating sits above a striking, high-contrast "military" checkerboard dial that serves as a canvas for the deeply cool, iconic yellow-and-black Poseidon logo. The layout features a light grey central disk surrounded by blocky, dark hour indexes filled with premium Super-LumiNova. At 3 o’clock, a neat date window adds daily practicality. The central handset showcases a prominent, high-visibility bright yellow sword minute hand tailored for sub-surface legibility, paired with a black hour hand and a sweeping seconds hand. On the reverse, the solid screw-down case back is deeply engraved with the custom Poseidon emblem, guaranteeing a professional-grade depth rating of 300 metres (30 ATM). Inside beats the advanced, Swiss-made Automatic La Joux-Perret (LJP) Cal. G100 movement. Chosen to meet demanding military power specs, this top-grade, 24-jewel calibre runs at a high beat frequency of 28,800 vibrations per hour (4Hz) and features high-end KIF shock protection. Equipped with a solid tungsten-wound rotor and is adjustable in 4 positions. This cold-water reference comes with its premium 20mm genuine Isofrane rubber strap, a signed buckle, and two NATO straps. The watch comes complete with its original Synchron tube presentation packaging and warranty card.
