![]() This ingenious V-shaped lever allows all the energy generated by the oscillating weight’s motion, whether clockwise or anti-clockwise, to be transferred to the main spring. Diashock also reduces friction to ensure optimum amplitude of the balance wheel.Ī Seiko invention in 1959, the Magic Lever greatly increases the winding efficiency of a watch and shortens the time needed for the main spring to become fully wound. Protection from shock is therefore crucial and the Seiko solution was to create Diashock, a device that absorbs impact on one of the most vulnerable parts of the mechanical watch, the balance-staff pivot. Even compared to other movement parts, this part is extremely thin, being only between 0.07 to 0.08mm in diameter, or about the same as a human hair. When a watch is subject to shock, as when it is dropped on a hard floor, the component most likely to be damaged is the balance-staff pivot, which is the balance wheel’s rotation axis. Water resistant to 50 meters.ĭiashock is a shock-resistance device. A scratch resistant Hardlex crystal is used along with an exhibition back that allows you to view the movement in action. The stainless steel bracelet has a butterfly-style deployant clasp for easy on and off. ![]() A date display is shown at the 3 o'clock position. The case has a polished finish and a radiant blue textured dial with silvertone hands and hour markers. The Presage series Seiko SRPB41 (known colloquially as "Cocktail Time") is powered by the 23-jewel Seiko 4R35 self-winding movement that can also be hand wound and hacked.
