First jump hour service, wheel question.

Question

Received and stripping my first jump hour.

The movement is no trouble. A simple 1 jewel pin pallet but the date/minute/hour (from the outside in) wheels are not budging. (Central pivot for seconds hand).

I suspect it has to be pulled off something akin to a cannon pinion but this being a particularly nice watch I want to wear I don't want to risk damaging it.

It's a Trafalgar Instantime.

Any pointers or ideas would be gratefully appreciated.

Thanks.

Yes, the seconds are friction fitted and can be removed using a pair of hand levers or .80mm screwdrivers inserted into the small slots seen in the picture.

Apply steady,  upward pressure...not too much because the seconds disc may warp if you push up too hard. Slow and steady. Here a link to a jump hour overhaul I did a few years ago

Thank you, this gives me a bit more confidence to attack it again tomorrow.

I'll take a look through your service link.

Much appreciated.

Have taken a look through and that is perfect for my question. It looks to be near enough the exact same movement, though yours is a bit posher, it has a jewelled pallet fork pivot. :)

thanks again.

    • To quote measuretwice from a previous posti g: In the common vernacular, hollow ground is used to describe the resulting parallel No matter how many years one has done something is always good to try to understand what others mean. Searching the Internet alsio helps https://toolguyd.com/lee-valleys-parallel-tip-screwdrivers/

    • If you've used properly fitting hollow ground blades for larger fasteners you know they can handle a lot more torque than a regular screw driver without damage fasteners.   The difference is so pronounced you just should not work on antique machinery/equipment with slotted fasteners without using hollow ground blades or you will botch up the fasteners. However, relative to the current debate, two things occur to me 1)  To get the performance noted above, the bit has be a very good fit in the slot.  My set has I think 85 or 90 pieces.  Without that selection and ability to find a perfect fit, their advantage pretty much disappears.    Is a watchmaker going to have a similar selection to ensure that perfect fit and futz about constantly checking microscopic differences in fit?  2) Performance is superior, but the metric is torque handling ability.  Does this even matter in watching making?   My limited experience suggest no.  otoh, if you are  regularly damaging heads of screws with taper blades than yeah, figure out how to get an assortment of hollow ground bits that work for you....but otherwise, why worry about it?   imo there is no debate to be had on what is superior, the debate is simply whether it matters given the torques involved. A young guy I know worked for Roger Smith for few years (talk about a learning opportunity!).....I'm curious on he was taught

    • yes sir, forgot to mention "cone shape",  the  ajuster is a good thing,  i have over tightened the staff in the past.  this one is "floating" almost 1/16 inch !   i decided not to tighten the staff.  it's back together and keeping good time. Thanks,  vin
