Model SW201, The famous Smiths Made In England elusive automatic wristwatch with the 25 jewel movement with nickel plated finish movement based on the 19 jewel movement. Designed by Richard Good and Peter Amis in London and built in Cheltenham. Copied directly from the IWC automatic mechanism of the period. Correctly signed on the movement Imperial. This is is a good timekeeper. Recently serviced with a new strap and crystal with any worn parts replaced.The pellaton winding system all functioning correctly. The case has usage marks but no dinks, and is the type without the writing on the back. The dial lacquer is slightly worn at 1 to 3 . This is the luminous type hands and dial markings.
I haven't tested this for waterproofing, The case diameter is about 34.8mm making it one of Smiths larger diameter watches. The case construction is all stainless steel with a clip on back which is nice and tight. Fitted with a new 18mm Buffalo grain mid brown ZRC strap, with the coronet logo which nicely reflects the Smiths one. .
