new ETA movement part


Recommended Posts

Maybe a simple question but I can't find the answer. Does a new ETA part require lubrication as advised in the ETA technical communication? For example for the 7750 it states, the driver cannon pinion and the hour counting wheel if cleaned you must lubricate. So if I get those 2 parts new should I lubricate them as shown in the communication when assemble?

Thanks for your help

The idea is that these parts come ETA per-lubricated when new.

I cleaned these parts once and then lubricated as the movement was neglected by the owner. Not a big deal, but if you bought new parts - no lubrication will be needed. Also, you may ask your parts supplier.

ETA parts come lubricated, the question is how old the lube is? so if you get a part made 25 years ago, would you just instal it and take pride in such accomplishment?

Same question applies when you have a fifty year old new unused watch in your collection.

I put the question to our knowledgable moderators here, the answer was, if expired you should clean old oil and relube.

Don't forget the epilame treatment. Special attention with reversers.

    • I'll have a look for it, but don't hold your breathe. Failing that I'll make another video when another bezel needs to be removed.
    • The UK lots can be a 404 hit or miss, 6 - 10 watches can come in anywhere from 20 - 50 quid. I once had a 404 division of 8 watches for a fraction over 30 quid, one of them was a Smiths Astral model National 17 an absolute certainty for winner contender. The crystal was scrached up to the point of being very difficult to see the brand, something triggered a gut feeling in me and it paid off.
    • I just picked up this Mondaine quartz watch on tradera.com for £11. It's a non-runner so I will replace the Ronda movement (£10.95 at Cousins), polish the case, replace the case-back gasket, and replace the mineral crystal. Now, the problem is finding a suitable crystal. The original crystal is slightly domed (2.4mm thick dome), measures 36.4mm in diameter, and is 1.3mm thick at the edge. The closest I can get on CousinsUK is 36.5mm in diameter, 3.1mm thick dome, and 1.5mm thick at the edge. I think the replacement crystal would look OK, but the problem is finding a suitable glass gasket. The case diameter for the glass gasket is 36.9mm and the closest glass gasket I can find on CousinsUK is either 36.8x36.0mm or 37.0x36.2mm. I guess one of those glass gaskets could work but as you can see there's no way the 36.5mm domed crystal would fit the inner diameters of those glass gaskets. I guess I will have to give up on a domed crystal, no? So, the backup plan is to use a (1.5mm) thick flat mineral crystal as the diameters come in increments of 0.1mm. But, what glass gasket would be the better option? The one with an outer diameter of 36.8 (0.1mm too small) or the one with an outer diameter of 37.0mm (0.1mm too large). Again the case diameter for the glass gasket is 36.9mm. I believe I read or heard that the crystal diameter should be 0.1mm wider than the inner diameter of the glass gasket. Is that correct? I'm sorry for all the numbers. I've tried to make it as clear as I could. So, I'd appreciate your thoughts on this. BTW, measuring and sourcing crystals and gaskets is extremely time-consuming! 😓
