Memostar Alarm - AS 1931 Calibre

This little alarm watch was sent in as part of a larger lot of watches won at an auction by a customer. The watches condition was unknown until it arrived with me but after a brief examination it was clear that it needed some tlc to set it running right again. The movement inside ( AS 1931 ) was rather soiled in excess oil and although the alarm function worked the main movement did not run. The hairspring was quite badly contaminated and in need of adjustment, the whole watch would need stripping down for cleaning before work could begin in servicing the watch.
As can be seen in the photos above the excess oil had seeped through to the dial in quite a large amount, someone somewhere had gone a little over the top on trying to get this watch running !
Time to strip the movement down and get it cleaned up >>
Once the movement was clean and the hairspring thoroughly decontaminated the assembly & lubrication could begin. The dial side is a little more fiddly than your standard movement but there were no broken parts or damages involved so it was straight forward to get the watch back together again. Unfortunately i forgot to charge my camera battery so i have no photos of the reassembly but i will remember for next time :)

With the watch fully assembled the movement was running good again and the alarm also working well. The glass was given a good polish to remove the scratches and a new strap fitted to finish the watch, overall a nice little alarm watch fit for purpose again ! :)

Hey there!

Many thanks for sharing your restoration. My father has just handed me his old Memostar and your pictures will be invaluable for when I start working on it.

The movement is in excellent condition the and the case is pretty reasonable considering its age and the abuse my father inflicted upon it. Sadly, the crystal is cracked (and chipped!) and will need to be replaced.

Unfortunately, I cant find any information about what crystal was used in this watch. During your restoration did you happen to come across any crystal part numbers?

Best,
Jon
