Hi guys, I am having a hard time figuring out what KIF Elastor spring to order on cousins to replace a broken one I have in a Hamilton movement cal. 61. I cannot find any databases that have any info about this movement but I am wondering what the difference is between the elastor 3-2 and 3-3 (what do I measure??).
Thanks for the help!!
I'm on the lookout for a Hairpsring for a Hamilton cal 770. I've managed to find out that it's a Breguet made from Elinvar but that's about it.
Does anybody know the parts number? If you also know where to get hold of one it would be very appreciated.
I recently got an amazing Hamilton Sea Cliff 3 watch from the early 70s powered by a handwound cal.61. I received the watch and it had not been serviced in a very long time. I serviced the watch but unfortunately used an oil pick that was too large to take the elastor shock absorbing spring out to get to the endstones. I accidentally broke one of the two levers off in the process and am now left with a functioning movement that I am afraid might become easily damaged by displacement of the endstones from small shocks. I have included a photo of the KIF Elastor spring below. I looked all over the internet, and i cannot find a supplier that will sell to me (not a trained or professional watchmaker). Does anybody know where I can get one of these springs? It would be greatly appreciated if somebody could lead me in the right direction as to where to get one and how to tell if it is the 3-3 or 3-2 sizing or even have any idea what ETA movement this cal.61 is based on as there is not a complete database of these movements online.:( Thank you everyone for your help!!
Here is my puzzle. I have a watch that I am working on. A Hamilton 987. It has been cleaned and oiled and demagnetized. When I run it on the timing machine the horizontal rates and the pendant down rate are all close and about +/- 4s/day. When I move it to pendant left things get weird. It has the same amplitude but the daily rate goes way off the chart -98s/day or something, also the beat error goes from 0.5ms to 0.0ms.
The hairspring is running unobstructed, and he regulator fingers are adjusted correctly.
How can this happen? How can a wheel spinning at the same amplitude produce such a wildly different rate? And how does the beat error change with the position change like that?
Hi all, i have another military watch - this time a Hamilton, this one is a customers brought in for a service. We know the date it was producded and various other info, how ever it does'nt have 'Hamilton' on the dial. We have also found there seems to be different style models with the same serial number. Would any of you military enthusiasts be able to give us any more info? thanks
Real quick question on repinning the hairspring to the stud. Should you remove the hairspring from the balance wheel in order to do this and to make it level or is it best to just leave it on the balance wheel? Any other tips and tricks to make this easy and smooth would be great. Thanks
