Even a lot of Seiko collectors will not have seen a Lassale pocket watch before.  Model reference 9550-5339.

HOW DO WE DATE THIS WATCH?

From the serial number on the the case back we can accurately date this watch to being made in September 1990.

CONDITION

Lassale were Seiko’s high end range of slim watches.  Seiko bought the rights to Jean Lassale’s name when his company went bankrupt, while Piaget bought the technology side of the business.  But a slim pocket watch is very niche, and this model was not even in the 1990 catalogue.  You have a slim case of just 4.7mm, which would make this very comfortable in a waistcoat pocket, and at 39.5mm wide it has nice proportions.  Condition is excellent, and the blue sticker is still on the case back.  We will install a brand new battery before sending the watch out to the new owner.  The 14 inch chain attached is the original, signed Lassale.

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