stuck speedy pusher

[n linsley]

last night at work went to set of the chrono but to my horror the start/stop pusher would not move after initial panic i tried the reset pusher which seemed ok, after a couple of tries of both pushers the stopwatch started and seems to be fine now. just wondering if anyone else has had this hapen to them.

The pushers are occasionally prone to sticking, especially the stop/start one. when was it last serviced?

[eptaz]

Yeah, it might be a gasket issue, or the pusher may need to be reattached.

The modern Speedies' pushers are push-on and not screw, correct, Kieron?

Of course, it might not happen again!

it was new last year,last night was the first time it has hapend it seems fine now just hope it doesn't hapen again,my heart stoped for a moment there.

Eric, the pusher tubes are screwed into the case from the inside, is that what you mean? The pushers are inserted from the outside and held in place with small circlips, again, inside the case. The seals are on the pusher stem if I remember correctly.

Sometimes if the chrono hasn't been used for a while the pushers can feel very stiff to operate too...

The same thing happened to me on my new Speedy. Fortunately I bought mine through the military Exchange so I taking it back tomorrow and exchanging it for another new one.

For your problem with the new watch I would go back to the dealer, or you could try a small amount of oil but I would hesitate to do this if there is still a warranty.

You may find it just stuck on the spline it slides on and will free up with use or never stick again. I have fixed sticking pushers by putting a drop of watch oil on from the outside to lubricate the splines. Don’t put any old oli on as it may damage the inner seal.

For your info….I renewed the pushers in an old case a while ago, the pictures below are not very good but it will show how they work..

The pushers are in four pieces there is a tube that screws into the case from the outside of the case. A spring under the pusher itself and a small screw pin is inserted from inside the case - this screws into the outer part. New pusher packets have two screws one longer than the other. The longer ones must be for other watches.

You first remove the screw pin from inside the bare case

Then you can pull the pusher off - it is on a spline - looks like a small gear.

Then you have to remove the tube by unscrewing it - There is probably a special tool for this, I used the old pusher head to turn it with a pair of pliers.

To reassemble, screw in the new tube – using an old head as a makeshift tool. Forgot to say there is also a small aluminum washer for the outer tube to seal it to the case, you get a new one in the kit and have to remove the old one from the case itself it fits in a small recess.

The pushers fit on to this with the spring inside them

The small screw pin is inserted from inside the case and this screws into the outer part It screws in fully and creates the spring loading for the pusher

I used a small quantity of silicon grease on the splines. The insiode of the pusher head is also splined and this is what it slides up and down on.

Don't try this at home unless to know how to get the movement out safely.
I would think a watchmaker could replace both pushers in 10 minutes

Best regards
