I have a Bulova sine plate with integral rotary table. It doesn't have any locking features for the plate so I don't think it was used for machining. The rotary can be locked and it does accept a dovetail block that can be clamped in place. Has anyone seen another, know what they were used for or when it might have been made?
First time ever trying to fix a watch. It's a Rotary Editions 500series. Opened it up and the part in the pic was swimming about loose only issue is I have no idea where it goes.
Any help would be greatly appreciated.
I have recently bought a 'non working' rotary automatic skeleton watch. I love the watch to bits however...
The watch will only work when fully wound and as it unwinds (with little wearing) it stops. it appears as though the minute hand is ever so slightly fouling on the hour hand. when full wound there appears to be enough power to override this. I'm hoping I can just tweak the hand very slightly to clear it. it visually appears slightly bent up.
Ive had the watch open fairly easily however I cant for the life of me find how to remove the stem/crown. ive searched high and low online and am now fairly familiar with the process on many watches except this one.
Any pointers would be much appreciated and well done on great forum.
In order to clean the strap of my wife's Rotary watch I need to remove the winder.
I've located what I think is the area that I need to work on (see attached pics). There is an arrow pointing to a lever that moves when the winder mechanism is pulled out. There is also a post with a dimple (there's probably a better technical term!) between this and the winder.
Should I be able to remove the winder by 1) moving the lever (and from which position) ... or 2) pressing on the post with the dimple?
Any help gratefully received before I damage a watch of sentimental value.
Had the head of screw strip off the mainspring barrel arbour. Tried to use a bergeon screw extractor and failed. So I set the arbour up in a lathe and graved a small cone center. Then I used circuit board drills and progressively drilled out the center. And after two broken bits, I finally got the insides loose. Then I went on my Stereo Microscope and picked out loose parts using rodico and a small pink screwdriver.
All worked well. Now to find a new screw. The main mission was to replace a broken mainspring.
And here is the broken mainspring.
