Hi peeps hope you are all well. Ive been after a nice set of vintage calipers for poising and truing as the ones i have  the elevator and indicator arm are missing. So put my bid in for a set that looked quite interesting and in good condition although a part missing but i could live with that. Unfortunately I've slipped up and didn't consider that the poising nibs were jewelled.  Which is great but the jewels are broken, one is intact but cracked the other has scattered completely. Looks llke someone has attempted truing a balance wheel on the wrong set of nibs. Just wondering if anyone knows if the jewels are replacable and if anyone has done this. The nib is replacable and unscrews leaving 3 parts, the nib with the jewel set in, a steel pin that pushes against the jewel from inside to accommodate a pivot and a spring to give force to the pin. TIA for any help.

      Fake Cartier?!?

      The edges aern't "Crude" they're time worn down. Take a look at a slightly better example: https://vintagewatchoutlet.com/products/cartier-tank-manual-wind-18k-gold-electroplated-vintage-1970s-mens-watch-23mm-1

      I looked around a bit for a similar case. Anyone find another example of the 18k gold ‘electroplated’…I guess snap-back case, with crude edges in the corners…apparently from the 70s?

      I'll stick my neck out here and say yes, I do. The dial's a bit iffy but the rest is fine. Not a great era for Cartier - the early 70's - has to be said. Gold/ silver plating (why not solid), etc. The OP expresses scepticism about the authenticity because one of the numerals isn't signed - usually the "7" as they are these days. Cartier didn't start doing that until about 2004. This is a '70's watch. That's a bit like someone expressing the same doubt about a Rolex Sub from the '80's - because it doesn't have the laser etched crown on the crystal or the engraving and the serial number on the rehaut. As I say - it was a low point for Cartier horologically - the early '70's, until they got their mojo back in the early '80's and started producing the iconic re-issue of the SS and gold Santos, etc, and then they were elevated back to where they belong; Watch as pure, beautiful jewellery. Interesting brand over the years.   Got a women's Santos on the bench at the moment - you can see the "7" hasn't the vertical Cartier - and this is from 1993. Nice watch - has seen some abuse. Always tricky to gauge what the customer expects me to do  in terms of Resto. Probably best just to polish it up a bit - you can - the gold bezel IS solid Gold - as are the screws on the bracelet. So, you see within 15/ 20 years of making the OP's ebay watch - Cartier had got their sh1t back together. Still a bit of a rubbish movement though - ETA by this time.

      Plated silver or gold doesn't have hallmarks.
