I got this stainless steel Smiths Imperial a while ago, but it was running very fast so I sent it away for a service and only got it back recently:
As you can see, it has a horrible scratch on the dial - otherwise nice enough.
The movement is Smiths own Cal. 0104 - aka the Imperial movement -
Described here: eBay.co.uk Guides - A GUIDE TO BUYING A SMITHS WATCH FOR PLEASURE OR PROFIT "19 jewels were only used in the Imperial or Everest manual wound movements. These are a later and completely different basic caliber with the faults ironed out, and a superior design with great ease of maintenance built in."
There is an ad here SMITHS ?Imperial? Cheltenham. Batch No 589 for a solid gold one designated 'batch no. 589' and ascribed to 1958. My movement is marked 588 - so it would seem reasonable to assume its a tad earlier - but the movement wasn't developed till about 1958/1959. Or maybe 588 means August 1958.
A good history also to be found on that same site: Information
The bracelet isn't original, but it came with it and suits it well enough. Some of these are being offered at very high prices on ebay so, for the record, I paid £62. If anyone sees a pristine dial for sale anywhere let me know!
