Seiko 1104A
Description
Seiko handwound movements are rather rare in Europe. Even more rare are those tiny form movement, which even contain a center second indication. Such a movement is the Caliber 1104A, which shows the high quality even of simpler Seiko movements.
The large balance with four legs is beared in an inhouse Diashock system and some of the jewels are located in chatons.
