Hello Folks!

I've just picked up for £1 a ladies 17-jewel Tissot watch which has lost its Crown & Stem. It bears the model number "17172-1" so was produced before Tissot introduced the "T" prefix. I have wound it a little via the crown wheel & it runs to time so it seems worthwhile seeking a replacement Crown & Stem. Unfortunately, Tissot UK cannot help even with providing the part number(s) let alone the parts themselves as it is too old. Cousins has replied to my enquiry to say that the parts are restricted by Swatch Group & are currently unavailable. I'd be grateful for any suggestions/information colleagues feel might assist my search - even a photo of a Crown & Stem from such a watch in case the parts feature in another model.

What is the movement number? Can you provide some pics please?

Thanks for your interest. There is a number on the movement which appears to be 6967183. Pic attached

Looks like the movement might be a 709 variant, as @mikepilk says there should be a number stamped underneath the balance.

Is the stem actually missing or is it broken off, in which case is there enough thread left, and room in the case, to use a stem extender. This might be an option if a replacement can't be tracked down.

According to windingstems.com the Ronda number for the 709 stem is 1330, a quick Googlefoo on Ronda stem 1330 does return results.

Its a Tissot 2451.

 There might still be piece of the stem in the movement , thats if the stem had broken. Worth to check.

No it isn't 🤣 @Nucejoe   Looks nothing like the 2451 on Ranfft. 

It does look like a 709 as @Marc suggests.

If you search ebay for "tissot stem 709" you will find some (assuming that is what it is)

That will be the serial number. The picture is not clear. I cannot read anything else.

Can you read anything under the balance

Thanks, again Mike. The number there is, I'm pretty sure - influenced by Marc's inspired guess - "709".

Thanks for that thought - there isn't though but it seems from other helpful responses that I have a way forward.

That's the one ! BTW is the small screw just past the 12 0'clock position in your photo the one to loosen when inserting/extracting the Crown & Stem ?

Thanks very much, Marc. On  following your ebay link I see, under the main picture, a Crown and Stem for sale: did you highlight just the stem in case the stem of such a combination might not be of the right length for my watch ?

if it's a serial number it's not a very unique serial number. It is probably more likely and what it looks like is a casing number. then searching for that we do get better pictures at the link below.

Buying an existing stem/crown combination always carries the risk that it isn't quite long enough. Best to get a new stem and fit it to your crown/case combination.

Cousins will be able to supply a suitable generic crown.

The stem was broken off but there was no thread left. Managed to get it out but had to remove dial as releasing the screw I asked about in an earlier response to you wasn't sufficient to get the stem to drop out. Was doing OK replacing the part of the keyless works I'd had to remove but securing it with Rodico while replacing the screw from the other side resulted in the Rodico fouling some of the nearby cogs. So I had to remove all the KW bits & clean everything up. During reassembly the part I'd removed to get the stem out pinged away from my tweezers ☹️. So a nice little hunt in prospect tomorrow......

Found it but then subsequently lost - & found - 2 other sub-mm parts before completing the reassembly. In the process I found that using my oilers as screwdrivers for some of the tiniest screws was an effective work-around! They were also useful for gently nudging parts into place - an approach designed to minimise the use of tweezers & hence the risk of further dispiriting 'pings'. When I had to use tweezers I found it 'safer' to use nylon(?) tipped ones even though their ends are quite blunt compared to my steel ones.....

      Omega sweep second pinion friction spring - correct tension IS important

      By TimeWerks · Posted

      Thanks for this post MikePilk, I just came across a similar problem with an Omega 1022.  The problem I had was the seconds pinion spring was bent out of shape and did not even engage with the wheel properly, so the seconds hand was not moving at all. (no power loss though :) I removed the automatic module so I could access the spring and work on it. Once I bent it back close to the right shape, I experienced the same problem you reported about power loss.  Many tweaks later, and the seconds hand is moving properly again, with amplitude back to good numbers again. Cheers

      After cleaning up the pivots, I made bushes on the lathe. At this point I've pressed in 6 bushes (3 sets) and the wheels turn smooth. What I can also tell you, is that I'm not looking forward to final assembly. Getting the pivots aligned seems to get exponentially more difficult with each wheel that is added.

      Greetings from Whidbey Island.

      Islands are interesting places to live depending upon their size and other factors. This is a bigger island and it has a bridge to get there at least on one end. It's also big enough that you don't have to go someplace else to get things typically. It can be a problem if you get a job in Seattle though. Yes I've known of people who commuted from the island to Seattle for a job and I don't quite remember how many hours it took but it took a long time. So basically islands are nice if you don't have to leave very often.

      What's your thoughts on this Rolex Sea-Dweller, ref. 16600, calibre 3135 project?

      Thanks @JohnR725! Everything you say makes a lot of sense and is encouraging to read.

      isn't it nice to have a decent case open or when the case doesn't want to be opened? In the case of a Rolex watch that supposed to pass specific water resistant testing you probably do need to tighten the back down. But they shouldn't be tightened so much that they risk stripping the threads out. Then the other problem that comes up is the gaskets can start to disintegrate and then getting the back off can be quite a challenge unless you have a really good tool and perhaps some penetrating oil to loosen things up. Yes really nice case marking. When I was in school we were taught to mark the cases and  the American watch and clockmakers Institute even had a? So if you joined at one time they would give you an identification number. They were explaining or giving an example of if the watches ever found in you have a unique number they can perhaps figure out the history of the watch or identify the body it's attached to for instance not that that probably comes up that often. So you got a unique number and even made a special metal stamp that you can purchase. It wasn't a super big aggressive stamp but still it left a mark in the back of the case. Then I heard from people at work on Rolex watches they were using a felt pen indelible but later on they decided that was bad because apparently the ink could release  chemicals although it seems like once it's dry that shouldn't be an issue. Then of course today was nice is you can keep computer records sealed have to mark anything at all I personally find it's best to leave no reference behind that you were even there. Especially when you have a beautiful watch that has no markings at all and now it has your scribbling all over it not good typically if there is a typical and watch repair?  a lot of minor repairs you don't need to do a complete servicing. But beyond a certain point you're going to have to take apart a lot of stuff you're going to disrupt the lubrication even if it looks perfect right now and yes you might as well just go ahead the service the whole thing. also in a watch like this where a lot of things seem to be going on the complete service would be better then you'll know exactly where you stand versus dealing with unknown mysteries for prior repair.
