Cow Rolex Restoration update 8 - look at this balance wheel! 

It certainly will be - my dad always likes a chat -

I stand corrected, I called it brass alloy because I wasn’t sure 😄

I am curious about this also. Does Rolex have a selection of hairsprings that have already been vibrated with that particular balance wheel?

It’s a fantastic tool. I’ve noticed that when Kalle demonstrates it in a video, the next few on eBay fetch up to £200. Once those with deep pockets who saw the video and want one have got one, the going rate drops to below £100. If you’re patient, you can save a lot of money. Be sure that the seller has shown/stated that both the jewels are intact and the frame is intact - most of them were made from pot metal and are easily damaged if mistreated.

@@mercuriall2810 Thanks for the tips.

@@GentlemensWatchServices You’re welcome. In case you don’t know already, it’s proper name is the BHT Trupoise tool, and was originally (briefly) sold as the Precista Trupoise tool. The original Precista and early production of the BHT version used much better metal for the frame of the tool. Most BHT versions are pot metal as stated before, but they’re still fine if they’ve been looked after. There’s no other tool which lets you test for truth in the flat and truth in the round, that also safely clamps the balance wheel by its arms so the bar can be used to push or pull on the wheel to make corrections. When you consider that balance wheels need to be true in the flat and round without deviation visible under at least 20x magnification, this tool really is a game changer for people who need to true balance wheels. If a balance wheel is distorted and isn’t flat and round to at least 20x magnification, you can’t hope to properly adjust the watch to positions via dynamic poising. Edit to add : the original instruction sheet for the tool is available online if you look.

@@mercuriall2810 Excellent, I knew none of that

If you search for round bubble levels and avoid the cheapest ones, you should find plenty of decent options.

If it doesn’t fit it is the wrong way around, hahahaha. The collet (inner bit), spring and stud (outer bit) aren’t symmetrical, so you see what is the right way up even before fitting the parts. Nice to hear from you.
