Important safety edit: Wear gloves or use nice block of soft wood if you’re using sockets to get the crystal out. I’m still feeling a couple of lugs in my palm, 24 hrs later.

Your reminder that sometimes automotive tools can help fix watches.

Had some fun on the work bench this long weekend with a vintage “VaLaire” 21 Jewel Super DatOMatic (by Mortima) dive watch that I (predictably) picked up at an online auction…and without considering the hints as to the size (the case is only…

My 80’s 17 jewels ETA 7750 Chrono have some day/date wheels that have seen better days. But most I can find with german day wheels are described as “2010+ movements”…

And if not a direct fit, what need to be done to make them fit – if possible?

I recently acquired a TAG Heuer Carrera Classic Chronograph 1964 Re-Edition CS3110 with Lemania 1873 caliber. The watch aesthetically is in good condition with no major dings or scratches. The timegrapher shows about +20spd with an amplitude of 260deg and 0.1ms beat error (lift angle 50deg).
It’s a ~25 year old watch with unknown service history.
I am planning on wearing it, keeping it, and passing it on to my kids.

Question: would you send it for full service now or wait?

I took it to my local watchmaker to see what was up.

Watchmaker found a shattered jewel on the minute wheel. He was able to clean it up but he said he’d never seen a movement with this…
