- Remarks
- Otsuka Lawtech's No. 5 Kai is a self-winding model equipped with three hour discs that move like satellites and a satellite hour that shows the time on a fixed minute scale. Movement is Miyota Cal.90S5 with our own satellite hour module, 28,800 vibrations per hour,aroundIt has a power reserve of 40 hours. Two reduction gears are stacked on top of each other to prevent the hour disc from slipping, and an extremely small ball bearing is used for the second disc. The case is made of stainless steel with a diameter of 40.5 mm and has a hairline finish, inheriting the design of No. 5 released in 2012. A box-shaped sapphire crystal windshield with a height of 4.6 mm makes the mechanism stand out, and the waterproof performance is waterproof for everyday use.
This is an unused item.
