Even a lot of Seiko collectors will not have seen a thin 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 November 1988.
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 is the second one we have been able to find. 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 very good overall. We will install a brand new battery before sending the watch out to the new owner. The 12 inch gold plated chain attached is unsigned.
This watch will be supplied with our presentation box and our Certificate of Authenticity.

From 1st September 2021 we will be planting a tree for every watch we sell, working with the International Tree Foundation (Est 1922) to make this business positive on carbon. By buying anything pre owned you are effectively reusing what already exists, but this takes it further and makes us feel good.
