In the Ofrei page, I found the part nr 145 in a Sellita SW200-1 parts page. The part is compatible with the following movements: BUL 1412.11, BUL 1413.11, BUL 1413.30, ESA 952.101, ESA 952.111, ESA 952.121, ETA 2801-2, ETA 2802, ETA 2803, ETA 2804, ETA 2804-1, ETA 2804-2, ETA 2805, ETA 2806, ETA 2808, ETA 2809, ETA 2810, ETA 2811, ETA 2812, ETA 2813, ETA 2816-1, ETA 2822, ETA 2822R, ETA 2824, ETA 2824-1, ETA 2824R, ETA 2826, ETA 2826R, ETA 2828, ETA 2828R, ETA 2829,ETA 2829R, ETA 2830, ETA 2830R, ETA 2831, ETA 2831R, ETA 2832, ETA 2832R, ETA 2836-2, KF 737, KF 738, KF 739, TIS 3108, ETA 2836-1, ETA 2846, ETA 2893-1, ETA 2893-2, ETA 2893-3, ETA 2824-2 SELLITA SW200, SW200-1, SW210-1, SW215-1 But the SW330-1 is not listed, although it states that it fits the ETA 2893-1 which is similar to the SW330-1. Maybe they forgot to include this movement in the list, no? Can we conclude that the 145 is in fact compatible with all those ETA movements, plus those Sellita? This would make my search easier.

Please post photos, I'm confused. I know what a case tube is but I would if thought that stem hole was basically the same thing. -
Maybe the movement was already replaced and it’s not the original. This could be very likely if it was originally a stop-2-go movement as mondaine stopped using them and they became obsolete as mondaine has the rights over that technology. Tom

I want to thank you all for your questions and suggestions. The case tube is definitely a fraction lower than the stem hole. I don't know if the tube can be knocked out of alignment, or even if it's the original movement, or a 'best-fit' replacement, but I've now checked both the old and new Ronda 763 movements and found the same problem with both. Without the case gasket the stem pushes the movement up at a slight angle. That must cause misalignment when it's all pressed together, the lack of pressure being why it works fine outside the case. Incidentally, also in the case, if I let it hover at the 'comfortable' angle when setting the hands. Is there a best practice solution to a problem like that? Is it safe/advisable to try to adjust the case tube in some way?
