Can Anyone Identify These Tools?

Hi, a while ago when searching on line I saw something I wanted in one of these 'watchmakers lots'. I bought the lot and after it arrived I noticed these othertools in there.

 

The first tool is brass and is 50mm in diameter. The grey areas you see are rubber. The holes are all the same and 9mm across. I hope the pictures say the rest.

 

The second set of tools appear to come in a set of sizes. At first I thought they were something to do with mainsprings, but now am not sure. There is a name 'Eterna' on the side of all of them with numbers from 1 (the smallest) on up. There is another number on some. These numbers are 1159 and 1319 which are Eterna calibers (I think), The interesting thing is that they appear to work consistent with mainspring winders, except there is no little tang for the spring to hook into. Where this would be is a cutting edge of some kind which leads me to think they could be a reamer of sorts.

I contacted Eterna and they have no idea. The lengths are approximately 100mm.

 

I am a bit of a fan of old vintage tools and I think its interesting how many 'spin off' hobbies can happen from general watch repair.

 

Hoping you can help.

 

Hamish.

The name eterna is a watch movement make. Clockboy could be right saying its M/spring winders could be for eterna watches but I don't see why you couldn't use them for any movements providing you have the right size. The flat looking disks I haven't a clue.

The disk thing could possibly be used to allow you to reverse the direction of springs for fitting in barrels. IE wind the spring in a winder, insert into suitable hole in the disk with the brass blank in place. Now twist the brass cover out of the way and press the spring into the barrel from the disk by pressing on the rubber.

I think that the Eterna winders are possibly for installing the slipping bridle into the barrel in the good old days when the bridle was a separate piece and the actual main spring was just an ordinary manual type spring. The clue is in the size of the winders arbor, it's way too big for a main spring. Just a guess.

Thanks Guys,

Yes I thought something to do with mainspring winders as well, but cannot see how it would work (looking at last photo) as there is nothing to hook the mainspring onto to wind it and also the size of the 'barrel' nearly displaces all the space available in the receiver. (Not sure if this makes sense).

It looks like a cutting edge on the barrel and it is sharp....maybe something to do with cutting or smoothing the inside of a mainspring barrel side? Then I don't understand what the cut out area in the receiver would be for...

Oh well...I'll just consign them to the back of a drawer...thanks for all your suggestions.

I've seen the first item for sale before (think I might even have one somewhere :D ) listed as balance screw & timing washer holder. I imagine the idea is when working on the balance to keep the washers with the screws they were on, and in the right order. Then it can be twisted closed to keep them safe - that's what I'm going for anyway.

      As a beginner, I’ve found this forum invaluable. I doubt I would’ve persevered without its support. I’ve had the confidence to attempt things that seemed to me impossible only because I knew there were patient and giving folks gathered around this watering hole, available to share their skill.    I would very much like to know where to go if this one dries up and everyone needs to decamp.  There’s something special about the folks gathered in this group.  How to keep in touch?

      Boley lathe motor silly question.

      By eccentric59 · Posted

      After a 3-week work fiasco that took up 137% of my time, I was finally able to get back to restoring a G. Boley 8mm lathe I picked up on eBay. I still need to do a bit of polishing on the tailstock but it works very nicely. Before and after pictures below. In any case, when I was reassembling the motor I wasn't quite sure which side the pully attached to, or if it matters. My question is ... does it matter? The listing photo below shows it the reverse of how I have it now, but it seemed that the cord and the reversing lever(s) should be on the right away from the belt.

      Deciphering mainspring specifications…

      By Zendoc · Posted

      Thanks Richard.  That’s clear.   So - another question - how much latitude is there in barrel and spring sizing? Say I have have measured the ID of my barrel to be 9mm and (all other mainspring specs being equal), the closest match I can find for a replacement mainspring is listed with an 8.5mm barrel size, is it acceptable to fit the smaller spring in to the slightly larger barrel without compromising anything functionally?  I’m in this situation now with an AS 1686 which has a 9mm barrel, but the closest replacement I can find has an 8.5mm diameter listed in its specs.  I can find an alternative 9mm spring, but would have to accept a different thickness.  I’m unsure how much wriggle room is acceptable, or whether in mainspring sizing, there’s a priority - ie thickness over barrel size etc. Thanks again for any info.  Cheers, John

      We already have a Facebook group run by Mark , so this is a bit moot. Search for “Watch repair lessons” group.   Tom
