Service: Seiko Bellmatic 4006-7010 calibre 4006A

IMG_0041Christian sent in this Seiko Bellmatic for a case polish and service.

This is an alarm watch with day and date display, so a fairly complex beast. The movement itself can’t be wound with the crown, but only the alarm.

I hope you’ll enjoy them as much as I enjoy Christians log. Continue reading

Not that I am a great fan of Quartz watches, but Seiko at least builds proper movements, and not the throw-away plastic trash that others put in their watches… Continue reading
