Hello I had a chance to acquire to two watch movement+dial sets which are from JLC and AP
However, I am having trouble finding cases to fit these.
Could anyone help me find cases that would fit these movements?
Non genuine cases are OK.
Hello dear watchmakers!
I am now working on a SU movement, Slava 2427. It is a manual-wind movement with day-date complication
I am trying to assemble the watch back together after service but I am stuck on the day disc.
The day disc is fitted OK in my view, teeth underneath the disc interacts with the click and the disc advances naturally as other motion works move clockwise.
However, the problem is that the days written on the disc are not in the right position and do not fit inside the day window of the dial.
What could I have done wrong??
Now I am working on a vintage bifora movement, Bifora Cal.812.
I have ruined the hairspring while trying to fix the position of it on the balance wheel to
adjust the bit error. I am searching for the balance complete or just the hairspring on ebay and other
suppliers but I haven't been lucky. May be I need other keywords for my search.
Could anyone help me find the part I need??
I am working on this vintage A.Schild movement and a jewel on the wheel bridge.
It is a jewel for the 3rd wheel but is cracked so needs replacement.
I measured the outer and inner diameter and they are 1.2mm and 0.17mm respectively.
Could any one help me find the replacement for this jewel??
I am always grateful for your help.
Hi All advise given is wise and should be noted, also consider lightening the inside of any desk/work place so as to give good reflection of light. My workbench is covered in white lino tile, a pale green as per the bergeon mats etc. as Marc says the roll top is probably the best option.
Thanks for the encouragement. I think it has to be a right-hand thread on the arbor, due to the direction the spring is acting. The mainspring did indeed have quite a bit of power left in it. There was a buzzing and a whirring for quite a while after I pulled out the balance, so it seems I have been very lucky indeed! I will check everything carefully again for damage. I have already found one cracked jewel.
That is (almost) identical to the part I have. Could not have wished for better support, thank you! I do not have the two holes in the barrel arbour, so I can't use a compass or similar to unscrew it. I will try gripping the circumference with something. The action of the spring suggests it is a conventional right-hand thread, correct?
Part of the stop-function (the disc with the finger on it) was missing when I opened the case, so it may well have been broken by another bodger who got there before me. I have the Maltese cross part. I may have a go at making a replacement if it's not too difficult. Would you have a picture of the part I need? How is it held in place?
