The 61GS family featured higher alterations and were called “Automatic Hi-Beat.”

These watches came out in the late 1960s and had the Seiko 6100 movement at 21,000 bph.

There were 36,000 watches produced for two models(6145-xxxx/6146-xxxx), in line with the 36,000 bph engineering in the movement.

This watch has a very standard dial design with a silver dial.


Completely serviced by our watchmaker in February 2020.

The plexiglass crystal is replaced with brand new in the last service.

The case was polished. It comes with 1-year warranty.
