This Hamilton Khaki, model 6313, has an ETA 22 jewel movement and a sapphire crystal, and an unusual but effective crown guard.

HOW DO WE DATE THIS WATCH?

From the supplied paperwork, this watch was sold by the prestigious Christ Jewelers in Zurich in October 2006.  But this paperwork has the incorrect reference number for this watch, so we have to now presume the box and papers were matched to the watch.  2006 may not be correct, we are still trying to determine when this model was launched.

CONDITION

This design has two distinct features.  The first is the bracelet – solid links on the outside, and dimpled plastic centre section which actually feels very strong.  The bracelet is not integrated, so if it is not for you you could wear this on any leather strap or metal bracelet.  The second is the unusual crown protector.  This C shaped clip pivots above the crown  to stop the crown either getting knocked or accidentally coming out, which would stop the watch.  It is a similar solution that Panerai use to solve the same problem, albeit this is a cheaper and simpler design.

The watch is in good order, with just light signed of wear.  The sapphire crystal is unmarked, and a nice sign of quality.  The numerals and the hour and minute hand are lumed, and this still is effective.  The chronograph has pump pushers, and measures up to 30 minutes in 1/10th second intervals.  The bracelet has been cleaned on our ultrasonic bath, and a new battery has been fitted.

This watch will be supplied with an original presentation box, the incorrect papers and our Certificate of Authenticity.
