Cousinsuk.com

Click "Watch Parts"

Then "Watch Parts Branded"

Then "Omega"

Then "Omega Case Parts"

Put the case number in "146.009" and click "Lookup"

Choose "Pusher" from "Case parts description"

Choose "Search All" from "Case part item colour"

Then "Search for items"

 

You will get two results, a Gold Plated and a Stainless Steel option.

 

The stainless steel option has the code: "086ST0002"

just looking at that picture of the screw measurements would a standard 6mm long 1mm threaded screw with a 1.2mm head do the job do you reckon?

What you need is exactly what I have sketched as your watch is identical to mine.

I think the best option is to get a replacement original pusher.

 

My reasoning: This is a wonderful watch - one of my all time favourites, although I don't currently own one. And, in my opinion, deserves the best care. Patching it up when the original parts are very available (and at a reasonable price) is, in my mind, not wise.

 

The screw does more than hold the pusher in place, it also is part of the dust/moisture sealing so if the diameter of the screw shaft is slightly out the watch can steam up quite easily.

 

Wether is is a big box of screws to go through, or making one up on the lathe, I consider it to be a far less desirable repair job than to replace with an original part when the original part is so available and costs so little.

Hi Guys my watchmakers screwdrivers arrived this morning but been at work all day apart from quick trip to the watchmaker. so first thing I done on getting home was set up a work station and away I went got the movement out although I have 1 case clamp missing! the crown and movement came out hassle free I've removed the old broken pusher screw. thought I might aswell have a look at the chronostop hand while its out you guys were correct it was loose. so re-seated and tested it nothing happened. but with some light of rotation of the movement the chronostop hand moves freely around the dial and after a few different rotations starts ticking away as it should, press button in and hold in on movement and it stops then on release will reset straight back to 12 position and is fixed there but on pressing button in again wont kick it into starting but hand becomes free to move again... any ideas what this could be? 

I have gone through the screws and found a few possible matches. Although now you've said that mark I'm thinking against the idea and maybe best of going for full new pusher. but even with new replacement pusher I'm stuck to as why the chronostop hands not working

 Regards Ben

It looks like the screw is stainless steel and not steel. If it worked and you could have sourced a screw it would have been a cheap fix if that was all it needed.

Mark that runs the forum would be an excellent choice if you are going ahead with the full service it requires. A lot of care is required with this watch, starting off with the second hand that can be very tight indeed to remove, mine pulled right off the mounting tube making things a bit more complicated.

    • Interesting interpretation of "traditional". I would say that Loctite is definitely the up-to-date and appropriate stuff to use, however, it is a relatively modern solution. Before the advent of such esoteric solutions I believe that the "traditional" thread locker of choice may well have been a sugar solution. Once applied the water would evaporate and the sugar would crystalise, locking the threads tight.
    • @steve1811uk close but no cigar 🙂 I don't smoke anyway. I checked in my stock of parts and that's the closest I got to your dimensions. Good luck in your search. @RichardHarris123 I have an accumulation of all sorts of odds and ends that I acquired as a result of buying up the tail ends of old watchmakers estates. Usually after all of the great stuff has been stripped out, which means that the sweepings off of the workshop floor can be had for peanuts, but if you have the patience, can often be found to contain gold (both literally and figuratively 🙂 ). These came to me through on of those purchases. I doubt that I will personally be able to make use of even 10% of my accumulated stock, but having it, and knowing what I have, means that I can at least pass bits on to those who can use it whenever possible.
    • Hi and thank-you for your suggestions, as per Mark's instructions I checked my browser "Safari" and spell check and grammar was not ticked. So all sorted. Thanks CJ
