GS Grand Seiko SBGW251
The first Grand Seiko recreated in platinum.
This model is the re-creation of the original platinum model which was produced in a very limited number. The manual winding Caliber 9S64 has been adjusted to an even higher level of precision, -1 to +5 seconds (under static conditions) per day, which is higher than any other Grand Seiko mechanical watch.
The platinum 999 used for this model has a higher purity than the 950 that is normally used for watches. The case bears an engraved and etched Grand Seiko logo, a rarity even among original models.
The dual-curved sapphire crystal is loyal to the original shape and gives the re-creation the same pleasingly gentle profile. The gentle curve of the domed dial toward the outer perimeter of the dial lends the watch its classic look, which is enhanced by the dual sapphire crystal.
The base of the dial is in gold, which allows the Grand Seiko logo to be particularly sharp in its outline and detail.
