Seiko sweep second hands are components utilized for constructing clocks from square one. The Seiko sweep second hands are so designated since they couple with specific clock motions made by Seiko. There are several things worth keeping in mind about both of them.

Sweep second hands by Seiko don't follow standard dimensions in terms of the placing hole. A lot of pins are created according to the American I shaft requirement, suiting mounting-hole diameters between 0.030 and also 0.031 inches as well as created to make a snug fit. Yet the Seiko conventional specifies spindles that are somewhat larger, in between 0.034 as well as 0.035 inches, calling for the matching hands made by the very same producer.
