Second Hand Moves, Minute Hand Doesn't... for ~10 Minutes

I have a rather odd issue on a vintage watch I purchased (Talis). It sets fine, winds fine, and runs. However, only the second hand runs for the first ~10 minutes or so after setting. Then the minute & hour hand kick in and it keeps good time for a long while (albeit 10 minutes slow). My best guess is a loose cannon pinion, but it seems odd that it would only be loose for a little bit, and only after setting. I've taken the pinion off, tried to clean any excess oil (none seen), but the issue remains.

My next course of action is a full clean and oil, but wanted to know if anyone had any ideas or something else I should be looking at.

Many thanks,
Seth

Does the watch set properly? If it's loose and difficult to set I'd look at the cannon pinion.

had a loose cannon pinion on a movement and it was behaving much the same way as you describe so I think that may be the issue. If so, you have to tighten it. I think there are videos covering this procedure.

It sets just fine. Easier than most of my watches, but not overly loose.

But I'm guessing it's a loose cannon pinion, too. Probably going to disassemble and clean, because I need to anyways, and also check for anything else odd. If after that it's doing the same thing, I guess I'm going to learn how to tighten a cannon pinion. Will update here with results.

Thanks all.

      Thought I had to share this - last time I cleaned out a deep fat fryer there was less mess than this. Another pin pallet movement. Unsurprisingly dunking it in Castrol GTX didn't fix the broken mainspring which is the only issue I've found.    Any tips for the dial? Also covered in oil.

      Hi Nev . No i didn't try this balance in the movement as it didn't run and the deformed staff broke when i removed the roller. Problem is what i think is the correct staff for this movement, the hub seat, roller and collet profiles are all too small for those parts of the assembly. The movement listed on Ranfft's site is correct my movement and the nos staffs i have match the ronda measurements. I can only assume that the wheel , roller and collet openings have all been broached to make them fit an oversized staff, both staff pivots had also been modified.

      B-Dip residue?

      Yes, threw it on the demagnetizer before I cleaned it to be sure.  This picture doesn't show it well, but I can definitely see liquid where the turns meet up.

      My newest 404 candidate, a late '60's / early '70's Waltham with a UTC 33 / Seiko 6601 17 jewel automatic movement. It needed a new crystal and I put on a strap from my Strap Graveyard. The timegrapher was a snow storm before servicing but it cleaned up nicely. I really like the funky font used for the hour markers.

      Hi Rich, the main problem with the balance is if the roller is from this movement. Did Yoy try if the balance interacted correctly with the lever? You can use suitable (by size) balance/hairspring couple from You pile of balances, but the roller must be for this lever (original for the calibre). Not that making roller is impossible, but it is easier to have one.
