Omega 23.4 cap jewel holder

[AlexanderToerzs]

Dear all,

Not really a walkthrough but something I wanted to share since I've never seen it before. I 've striped down an cleaned a 1935 made Omega 23.4 SC calibre. Losened the balance spring stud and removed the balance wheel to take off the cap jewel when I found this piece of pure swiss mastery:

The regulator, regulator arm and cap jewel is one unit which is held by  three pins and a slotted disc serving as a bayonet lock. When you insert the screwdriver into the centre slot and turn everything comes undone and falls out. Like so:

You can very comfortabley grab the cap jewel now by the "handle" and clean it with peg wood in the benzine jar. The caliber is small - only 23.7mm across but the parts are so well made that putting it together again is a matter of seconds. I'm really impressed.

All the best Alex

Same design can be found on Omega 30T2 Rg, which is 30mm calibre. I've seen it on Omega watches produced between 1935 - 1944, according to serial numbers.

Thanks Poljot, the period between the wars is my favorite watchmaking era. Industry alright but with a hand-made touch.

Cheers Alex.

I love 30mm Omega watches, especially in a slightly larger cases with 19 - 20mm lugs. Very classic look. And also, the movement itself looks flawless.
