I love these for measuring small pivots. For straightening pivots, I find I have much better luck holding the part in the lathe, turning by hand to find the fault, and use blunt nickel tweezers heated in an alcohol flame until almost to hot to handle to coax the pivot back straight.

Do you clamp the balance arbor and bend the pivot or do you clamp the bent pivot and adjust the arbor?

In clockmaking, we clamp the shorter part and use the longer end for adjusting. We can even straighten bent arbors this way.

I hold the staff (in the balance), get it running as true as possible, and bend the pivot with the hot tweezers. There are Dumont tweezers made just for straightening pivots (# 8), but they also can leave marks, the nickel tweezers work great. Of course if the pivot is too bent to start with there's no way to get it straight without breaking.

I can’t recall where I saw or the precise turn of phrase, something about the watchmaker must decide if they are the type to break their pivots efficiently and economically with tweezers or if they prefer the expense and precision of breaking them slowly with the Seitz tool…😒

I once asked my mentor when do we straighten and when do we repivot?

His answer was to try straightening first and if it breaks, then repivot.

So my turn to be the tool...of the day. A quick search and I can't find another one like it, perhaps because I don't know what to search for. Wassthis?

...a hole gauge of some sort yes? Hands? How to use it as there are a few numeric labels but not sufficient for the gradients of the sticky out bits...

Difficult to see in my photos but there are sharply defined edges as the ends get larger towards the middle, and they are smooth and polished, not textured like a broach, so I’d say no…but honestly I do not know what it is for…😒

Hard to say Rich, ive not seen one of these, if the steps are tapered then i would guess maybe, but the steps would stop you furthering any reaming, unless the other side can make a continuation.   If cylindrical then maybe a hole gauge , a measurement of the steps might help to figure out the stamped numbers

See the numbers 60 to  120 on one side , so 0.6mm -1.2mm.  Then a continuation on the opposite side 130 to 200 , so 1.3mm to 2.0mm.  Range from 0.6 to 2.00mm

A Star staking set UK peepsies, this was relisted today as nobody put an offer in around the 150 mark. The seller may not want to risk another non sale fee and sell it early on in the relisting, this has worked for me a few times. My thoughts are an offer of 100 a bit harsh but 110 might take the seller's attention. I have Star, a set bigger than here but this has some interesting stakes i don't have, a couple i know unlikely to get used like the cylinder stakes but even so for 110 plus del. Could be a fair starting set. If interested ask questions to get input from others more knowledgeable than I.  Oh also it has sink rollers and some other countersinks so providing it has the reamer spindle to hold them then a nice little addition.

So I've finally identified this thingie- there's a lovely post what shows this jewel gauge...and everything you wanted to know about watch screws....

...helpful for me as I have cased a watch I have posted here previously and the movement ring is unfortunately a bit wonky, so I'm down the rabbit hole of sizing and locating case clamps, screws et al...

I've been on the lookout for these or a more modern alternative, nothing available under 2mm ,mostly bigger engineering stuff.  The hand gauge might be the closest idea for measuring jewel holes above 0.3mm. For any holes within a plate or big bridge the individual gauges would need to be removed, but that leaves the gauges without thd size markers.

Yah the hand gauge is readily available- cool for hands but not much else...

...for fun I checked on eBay for the Swartchild gauge- krikey! One for $70US in Canada...I guess I'm there was one floating around in my Seitz set as a bonus, even though I don't know what it is🤣.... Oh the economics of horology...

...and here's a tool likely we all use but for me in a new and very helpful way- one of those honkin' stumps of peg wood for barrel arbor fitting...

IMG_0803.thumb.jpeg.0520885bfbac8dbc921d2d06df85777a.jpeg

It grips the barrel sufficiently, then I counter rotate the barrel opposite the spring so the arbor hook drops right in!

...what was once kind of a fiddly job takes only a minute. Thanks Kalle!

This seem to have a good watchmaker range .

That would be a nice complement to a set of jewel gauges like these. I lost access to the shop when I retired, so now I have to get my own darn tools. I think the set you are showing is UK only, though, and shipping to the US might be prohibitive, otherwise I'd consider that set for myself.

I bought these pin gauges a few months ago, as well as the 1 mm to 2 mm set. They are bang-on when it comes to their thickness. Really helps when re-bushing, so you don't have to remove the bridge or mainplate to measure the bored-out hole. I've got a set of Bergeon pin gauges measuring 0.07 to 0.5 mm, which cost a small fortune but couldn't do without them for smaller work and measuring the inside diameter of jewel holes.

The same seller does pin gauges from 0.1 to 1 mm

Hey all watch peeps, i trust we are all in good health.  I have another tool for us to identify,  this time i don't know exactly what it is.  I thought I had seen it described a year or so back by an ebay seller but i cant quite figure out how it works per the description.  There are various sized drill bits and taps and a brass holder with 2 removable ends.  Yes its for making a hole and then threading that hole but for something in particular on a watch. What might that be ? and how exactly does the tool do that ? Its open to anyone that knows becasuse i dont know for sure 😄

typically I ignore this discussion because a while back you put a restriction on who could answer. in other words on some previous tool you perceive that it would be too easy for most of us you're looking for others to use their imagination as to what it can be. Strangely enough this tool falls into that category doesn't it?  mine is lurking in the bench I don't think I've ever actually used it. For the most part is typically not something I would do at least with normal watches. Then I don't think I've ever seen instructions on how to use the thing.

But still it does make for a nice mystery tool the clues are in his description but?

Hey John, yes some mystery tools are just too easy for you pros, its good to give others a chance of guessing it first This i didn't think really fitted into that category, i dont really know what it is for maybe i should put a time limit before professionals give us a definite answer. We can see that its used to drill a hole and cut a thread but in what exactly?  I think it has a specific use and maybe something else besides the drills and taps fits into the brass holder.

    • Out of curiosity I don't suppose you want to share the prices? Yes it would be cheaper to get a Chinese clone but this is not a Chinese clone this is a Swiss 6498 and the last time I looked brand-new movements are extremely expensive. I see the answer has materialized before I Finished this I'm still curious genuine Swiss because as I said the last time I looked they were rather expensive. Although taken a quick look at eBay it looks I can get a movement For approximately $130. Otherwise I'm seeing silly prices starting at $400. This is the unfortunate problem of anything that is well watch repair Somebody in there before you that didn't grasp what they were doing and now you have to pick up the pieces. It seems be unfortunately the world of the watch the more pieces of the stuff you have to deal with. I suppose it's a miracle that in the watch runs at all. On the other hand the number of amateur parts destroyers of watches versus the quality of watches well that's probably a good thing that there only a tiny percentage of

    • I think you misunderstand what I was getting at I was quoting you. You're the one who found the color Rolex manual and that's definitely worthy of an acknowledgment.   So you don't need to apologize for anything I wasn't offended. As I said I was quoting you because you brought something exciting I color Rolex manual a PDF color manual. I just wish you'd remember where it came from and whether they had any other color or any other Rolex manual's.
    • Hi all,  I am currently working on a tissot 2481 (equal to an omega 1481) and have tried to replace the mainspring, I ordered the correct spring from cousins but the centre spiral wasn’t tight enough for the arbour, the only option I had (with limited skills and knowledge) was to bend the spring to suit, after several attempts to get the correct size it led to the spring snapping is there an alternative mainspring suggestion as it seems it is the cousins Swiss one I’m having the issue with or does anyone know where I can source a mainspring barrel complete? thank you in advance Sam
