In recently for a service is this lovely little Arly Triple Date featuring a Venus 203 movement, although running it did require a service to bring it up to date. The watch packs a lot of features for such a small package, day, date, month and a moonphase at 6 O'Clock all cased inside a gold plated case with three pushers for rapid date change. Breaking the watch down for service is a little different as the pushers get in the way of normal removal and foul the dial so careful removal of dial & hands first before stripping the movement.
With the movement uncased we can begin to carefully remove the worn pushers and se about cleaning them up. Years of gunk can build up unnoticed quite easily and affect working parts >>
With the casing cleaned and the pushers ready the movement could be stripped down and cleaned, the 203 calibre is based on the Venus 180 with an additional date plate and complications added. If you should find yourself in need of parts for a 203 then the base parts of a 180 will work just fine.
With the movement cleaned and reassembled timing had improved and the date functions were now much smoother due to the pushers being cleaned out of that gunk. There were a few minor issues but nothing that did not get resolved so it was time to re case the watch with a new glass and send it on home. The original crown had long been replaced but did not look right so was replaced with a signed Alpha crown which looks more fitting to the watch.
Still to come we take a brief look at the IWC TCZ movement design based on the ETA 2893, a Tag Carrera in for a service and also a look at a recent Rolex Ladies 2030 calibre :)
