Sought after automatic Seiko Bell-Matic, model number 4006-6060, with mechanical alarm feature and blue dial.


We can date this perfectly to being made in September 1975 by the serial number on the original case back.


This watch is in fantastic condition, with the only small marks on the case near 5 and 11.  The dial is superb, even under a loupe it is difficult to see any dirt or damage. The alarm is very accurate and loud, operated by turning the internal bezel via the crown and pulling out the button at 2.  The date can be quickset by pushing the button in at 2, but the day has to be set manually.  The date wheel is in English only.  At some point the original bracelet has been replaced with a blue leather strap, which compliments the watch well.

This watch will be supplied with a presentation box and our Certificate of Authenticity.
