GRAND SEIKO Mechanical Manual Wristwatch Men s SBGW231
Classic hand-wound mechanical 3Days that brings out the appeal of adults. A model that once had a hand-wound caliber 9S54 came out with the caliber 9S64, which evolved with the classic design intact. The maximum winding lasts for about 3 days. By adopting the latest hairspring and escapement (ankle, escape wheel) using the MEMS method, the stability of accuracy during actual use has been improved. The soft rounded dial, the needle bent at the tip along the dial's roundness, and the box-type sapphire glass that revives the classic classical form are in harmony with the tasteful ivory dial. The classic style is complemented. The hour and minute hands that are carefully polished in a ridge-cut shape, and the shin leg of the case that has been subjected to a rough polishing shines beautifully under the light. The back cover has become a see-through back specification, so you can see and enjoy the movements that make the mechanical movement splendid. / Caliber: 9S64 / Driving period: Maximum winding time lasts for about 72 hours (about 3 days) / Accuracy: Average daily difference +5 seconds to -3 seconds (static accuracy) * Accuracy standard when carrying is daily difference +10 to- 1 second / number of stones 24 stone / second hand stop function / waterproof for everyday life / back lid with emblem of lion / see-through back / 6 screws fixed back lid / 1 type of anti-magnetic / made in Japan
