|Waltham 1888-American Watch Co, 19J, 1893.|
This is an exceptionally rare watch, one of the top watches of its day and now even more sought after than the Riverside Maximus which later replaced it as the top 1888 grade. It gains 3 stars for rarity in the price guide - and they are pretty stingy giving stars!
The size 16, split plate movement has 19 "Extra Fine" Ruby and Sapphire jewels, a Swiss lever escapement with a Breguet sprung cut compensated balance with double roller and a "tadpole" micro adjuster. The train is gold as are the top jewel settings and balance screws, it is adjusted for temperature, Isochronism and in positions. Crown wound and set.
The serial number shows that this one was made between April and June 1893.
The "fancy" dial on this example is a collectors item in its own right, there are a couple of very faint cracks in the glaze that take some finding, but these are fragile dials and this one is almost as good as it gets.
In a 20 year, Filled gold case and with the standard dial the retail value in the US is between $2,000 and $3,500, about the same or a bit more in pounds in the UK.
A full set of very high resolution pictures of this watch can be found here on Zenfolio. At the time of writing this watch is for sale from my website at £2,600.
