Hi guys. I have finished the Breitling 13381 Avenger with a 7750 cal movement rebuild and all is functioning okay. I purchased 2 pusher tubes complete from Cousins. I now need to remove the original pusher tubes and replace them.  Is there a tool for this?  Here is a pic. I do not want to damage or scratch the case so a proper tool is desirable. I will heat up the case to soften any sealant that may have been used on the original threads. Once I have completed I will take time to post up all my horological photos to this site. I will change my camera for a more easier to operate model doing macro photography. I will probably need help with that from a learned person here at WRT.

Thank you guys for all you are and all you do.

You can find a good chinese one on the various outlets for a fraction of what youll pay from the watch repair shops. b6e428796cf72bc5077d306b2b3604c4.jpg

I have removed tubes before using a cutting broach & just twisting. This might be worth a try providing you re not to zealous. 

Ps I don't think they are screwed in just friction fitted but they might also have had touch of loctite added hence go gently if you try my method as what you don't want to do is damage the case.

The tube has a castellated top with 6 indents. The tool I imagine I need must have six teeth to engage in the gaps. Here's a better picture of the new pusher complete with tube. I have highlighted the castellated part with a spudger.

Thank you all for your help.

I have looked at the Cousins offering and it does not appear to contain the right tool. Maybe Marks comment that you cannot get case parts and tools for Breitling is here to haunt this watch repair. I hope I can find a solution.

Ok I remember now !!. I could not unscrew the old tube because it was stuck solid even with heat and tapping it, it just would not move. I left it and just replaced the pusher. Also what made this more difficult was the Avenger I was working on had a  titanium case. I presume there is a specialist tool that is only available for Brietling engineers. 

PS:  Parts availability is now one of the most frustrating elements when servicing watches.

I could be wrong but I think the way most are made is there is a tube that goes into the case and that tube is either threaded or press fit. I think the pusher assembly is the same way. Either way that pusher pictured looks like the threaded type.

I just removed some about 2 months ago to polish a customers Avenger case and bracelet. A special tool nor heat is needed. First the pusher buttons are removed from the threaded castle shaped housing then I used a piece of brass flat stock to go across two of the notches and twist out just like a screwdriver removing a screw. If they are really tight just twist the brass flat stock with a pair of pliers. If you dont have brass flat stock a penny thinned down on a piece of sandpaper and inserted across the castle nut notches and turned with a pair of pliers would work just the same. (Use a pre- 1980's penny they are solid copper) also I highly recommend removing the movement from the case and cleaning the old loctite out of the case side pusher threads. If you dont there's a chance of pushing bits of the old hardened loctite into the case and stopping the movement. I reinstalled the pusher housings with a drop of purple loctite on the threads.  Good luck.

Thank you Clockboy and Bullseye. Much appreciate your advice.

I will try Bullseye's method first. I have some brass stock. If push comes to shove I will try and remove the pushers and use Clockboys method. I'll let you know how I get on. I will do Friday.

Hi All

I have managed to to remove the original pusher tubes which were thread sealed. This is how I did it.

I have a USB soldering iron unused so there is no deposit on the tip. The tip is pointed and tapered and 5mm in diameter. I placed the tip in the pusher tuber for about 20 seconds then using a piece of flat brass plate in the castle slots  with a small amount of force turning anticlockwise the pusher tubes were release with no damage to the case. Thank you people for your help.

The new pushers I purchased from Cousins do not fit the 13881 case they are too big and the pusher stems are too short. I tried to return them but no joy. I still need two pushers even if without tubes. Can anyone suggest a supplier?

Cheers

    • Hello all, just disassembling to service, but I can’t figure out the working of the calendar work…it’s not operational the jumper and spring are ok, but the operation of the driving wheel has me at a loss. I can’t see a cam to drive anything. Is something damaged or missing? Help please!
    • Believe the relume (not a fan) was done a long time after the damage. 
    • I can only think of some chemical reaction to reluming
    • I have a little milling attachment for my WW lathe, but very rarely use it and not for wheel and pinion cutting. For that I use a small Sixis 101 milling machine. I normally do direct dividing, but sometimes have to do an odd count and use the universal index which also fits on the Sixis.   Back in the day when I didn't have a mill, I would cut gearing on my Schaublin 102. It has a universal dividing attachment which fits the back of the spindle. Both it and the one for the Sixis are 60:1 ratio, and with the set of 4  index plates I can do almost any division. When I've had to do a strange high count prime number, I print a disc with the needed division and just place the plunger on the dot. Any position error is reduced by a factor of 60 so still plenty accurate.   The machines are a mess in the pics as I'm in the process of making a batch of barrels for a wristwatch 🙃.   This is the Sixis. The head can also be placed vertically, as can the dividing spindle.   Dividing plates. The smaller ones fit another dividing spindle.   Universal divider for the Sixis. I put it together with parts from an odd Sixis spindle that takes w20 collets, like the Schaublin 102, and a dividing attachment from a Schaublin mill.     The dividing attachment for the 102. The gear fits in place of the handwheel at the back of the headstock.   And the little milling attachment for the WW lathe. I just set it on the slide rest to illustrate the size, you can see from the dust on it it really doesn't get used much. I think only when I change bearing in the head, to kiss the collet head seat (grinding wheel still in the milling attachment).
    • I read a lot about the quality (or lack thereof) of Seiko's 4R, 6R, 8L  movements...or more specifically the lack of regulation from the factory. Especially when compared to similar priced manufactures using SW200's or ETA's. I thought I'd ask those more in the know, do the 4R's and 6R's deserve their bad reputation, is it fairly easy for someone with minimal skills (or better yet a trained watch mechanic) to dial in these movements to a more acceptable performance.    For background I spent more on a 1861 Speedy years ago, expecting that the advertised 0-15s/d  would probably perform more like 5-7s/d. In reality it's been closed to 2-4s/d.
