Specialize with Seiko Sweep Second Hands

Seiko sweep second hands are parts used for building clocks from scratch. The Seiko sweep second hands are so marked because they couple with particular clock movements made by Seiko. There are numerous things worth noting regarding both of them.

Sweep second hands by Seiko do not comply with typical measurements in regards to the mounting opening. Most pins are created according to the American I shaft criterion, suiting mounting-hole sizes between 0.030 and also 0.031 inches as well as developed to make a snug fit. Yet the Seiko common specifies spindles that are somewhat bigger, in between 0.034 and 0.035 inches, calling for the matching hands made by the very same maker.

Though the distinction between both criteria is only 4 thousandths of an inch and imperceptible to the nude eye, the hands for the one will absolutely not collaborate with the motion for the various other. Therefore, we suggest selecting the motion initially according to your specific standards (each kind has its benefits), and after that seeing to it to combine it with hands made to the same requirement.
