Is there resource that lists alternative designations for things like balance staffs?

 

I need a U936 (according to Ranfft) but I can't find one listed anywhere.

It's ironic that of all the movements I have I've managed to identify one and find the parts are not available lol.

Last night I was wondering if I need to learn how to make them - it would solve a lot of problems.

I have a balance that says H.P 16" . When i googled parrenin the name H.P came up . It has a brequet coil. As well as some 40 and 60 parts. That also says H.P on them . So think it could be right.

I know this is probably obvious - but how do I identify the calibre? This seems to be one of those things that's so simple and obvious to watchmakers they don't define it and it's a mystery to me lol.

Only think there are two different  H. Parrenin in 16 ligne. They are different height so check which height your movement is.

      Second hand watch market.

      By RichardHarris123 · Posted

      I'm not sentimental, I see it this way.  I inherit something I  don't like, I could sell it, buy something I do like and remember the person with the new item.  For example, I  inherit a watch ( I haven't), I don't like it, I  buy a watch I do like, every time I look at the watch, I think of the person.

      A lot of it has to do with a generations attitude.  Have we reached a generation of folk yet that have no sentimental values ie. Just an object to sell . I expect my kids will sell my collection , maybe keep one valued piece. Not being in the game very long, i have no idea when the sale of old watches boomed or if it has even reached its peak yet. If we go back 20 years what were ebay sales like then, expense wise and volume ?

      Omega cal. 565 - low amplitude

      By JohnR725 · Posted

      can I ask why you're not happy? did you notice that the acceptable low 24 hour amplitude of this watch is 160°? is there any possibility that a watch company could manufacture a watch that could actually run at a low amplitude and keep time? so if they can run at 160° at 24 hours and keep time then they probably would keep time at 240° which yours seems to be doing? then if you're really unhappy with this I would recommend purchasing an original Omega mainspring. Just because the aftermarket have numbers like an Omega mainspring it doesn't mean it's the same thing. Then I would also recommend replacing the escape wheel and the pallet fork. This is what they do in the Swatch group service center if they are unhappy with anything on the other hand they have an infinite supply of spare parts.

      That was reason for asking for mark's input, i wasn't sure if going ahead with dealing with the contact information would be particularly well received. @oldhippy thoughts ?

      @JohnR725 has pointed out many times that the Swiss don't care about amplitude, the timekeeping is the most important.  Give yourself a  pat on the back, great beat error and timekeeping, nothing to be disappointed about.
