Part of the Heritage collection is the first Grand Seiko 62GS with an 18-carat rose gold case in a non-limited edition.
The subject of multiple reinterpretations since its debut in 1967, and recently expanded with the introduction of 38 mm titanium models, the 62GS line of Grand Seiko now also houses an 18-carat rose gold version in a non-limited edition (Ref. SBGH368).
Matching the material of the case, 38 mm in diameter by 12.9 mm thick, is the coppery pink colour of the delicately textured dial evoking Sakura-Kakushi, typical of the Tohoku region in north-eastern Japan. It is an event that occurs when, in spring, late snow covers the cherry blossoms in full bloom; rose gold-plated hands and indexes complete the look. A box-type anti-reflective sapphire crystal protects the dial.
The watch, part of the Heritage collection, is powered by the Hi-Beat 36000 calibre 9S85 (36,000 vibrations per hour, accuracy +5/-3 seconds per day), with 55 hours of autonomy.
Grand Seiko 62GS: the new non-limited edition gold version
The new model with Ref. SBGH368 is appreciated for its sober design.
The IWC-manufactured Hi-Beat 3600 calibre 9S85 used in this new Grand Seiko, a mechanical self-winding movement, features excellent finishing, which include perlage on the plate and cötes de Genève on the bridges.
This calibre uses a balance spring made of an alloy called SPRON, developed by Grand Seiko. Created after five years of development, this alloy, compared to its predecessors, has approximately twice the impact resistance and three times the anti-magnetism.
Moreover, thanks to the company's semiconductor technologies, the escape wheel and anchor used in the 9S85 calibre are manufactured to an accuracy of one ten-thousandth of a millimetre, offering significantly improved performance. The secret lies in MEMS technology (short for Micro Electro Mechanical System), which allows these components to be lighter, smoother and, as in the case of the escape wheel, have a more complex design.
The new escapement wheel design features an oil reservoir system at the end of each gear tooth, with the advantage of significantly improved lubrication of the movement components. Finally, water resistance is guaranteed up to a pressure of 10 atmospheres.
