I've been doing a 1970 Oris Chronoris up that I bought wit, amogst other things, a missing minute wheel crown. I bought an Oris branded one from Cousins and relaised there was something amiss with the stem. I had a look and teh picture is as below. The stem hasn't snapped in anyway I can see it was made with that taper so my question is what type of split stem woulld fit that? You can see the winding wheel with the stub that protrudes into the tube, it can't physically fit in the otherway around but all the split stems I've seen are like a ball and socket affair. This has no flats on it. Can anyone offer any advice? Information on this watch seems really very sparse.

It's an Oris 725. Generic image below, the crown I'm having issue with it the highest, knurled on. You can see the winding wheel below it. I have a parts sheet which I've attached and the above part is 1442, you can make out that the part hasn't snapped if you zoom in on the general shape of it but I can't see anyting else that says stem or similar. The watch has a winding stem, a chrono pusher and a minute wheel/crown so there is the winding stem and no more.

      Balance cock stud screw

      By Neverenoughwatches · Posted

      As Richard said, this is a really old school trick for joinery.  Cut i strip of paper, might need to be watch paper  around 1 " x 1/2" lay it over a staking block then press the stud screw into and through the edge of the paper upto the head of the screw. You probably wont even need to pull the paper away the head will pull itself through.

      Waltham 6/0 d winding stem

      By ooteenie · Posted

      Hello,  i am looking to source a winding stem (winding arbor) for a waltham 6/0 d movement. I have found some that claim to fit 6/0, 6/0s, 6/0b etc and somealso claim they will also fit the d as well. The d does have hacking which is driven by the stem seating completely. Given some of the costs of these, i was hoping someone would know of any interchangeability with a source, or know a source where a confirmed 6/0 d stem can be had. I am in the US so a US dealer is best.    thanks in advance.

      So great to see and hear- your mum looks great! …my mil had a stroke last summer in the golf course parking lot. I’m flying out tomorrow to visit and play golf. she’s ornery because she can’t get off the tee but I hear she makes up for it on the greens since she’s been putting since a week after her stroke 🧐…
