I think you made a typo, I'm sure you meant to type 'Kif Spring Tools' https://www.cousinsuk.com/product/kif-shockspring-tool

@rodabod It says it has an adjustable stirring speed 100 - 3000rpm. I'm going to give this a go. I'll report back how things went.

Hi Nucejoe A quartz watch is no different than a mechanical one apart from the fact the Battery provides the voltage/current the block interprets this, The crystal vibrates around 32,768 times a second the block divides this down to normaly one pulse a second which is output to the coil which causes the step motor to pulse once, this turns the gear train and then the hands. Some watches pulse once every 4 secs or 6 secs depending on the make. As the current drawn is in micro amps it doesnt take much to affect the module ie dirt and old oil or even the wrong oil should be 9024 and 9027. The attachment explains both the mechanical and the quartz. regards Witschi Training Course.pdf

Oh crap, he found me!!! Funny facts: I was told, that he could actually not remove a spring like me before without pinging us away! Not even once! What was he thinking!!?? He just got lucky finding us, like now. I thought that he would never look under his pedestal.

I'd watch the seconds hand for a few minutes and see if you observe it ever stuttering. Of course, the easy option is if you have a quartz measurement tool, but most of us don't own one.

Hi Nucejoe A dirty mech, gummy train, and a gummy rotor bearings also debris attaching its self to the magnetic rotor to name but a few problems, usually a dirty mech. What make and caliber is the watch cheers

Sometimes the only way to get parts is to get a donor movement. If dealing with older watches especially (and your movement dates from 60's/70's) then the simple fact is that suppliers don't have the parts lying on their shelves. And when it comes to things as simple / generic as a spring you're even less likely to get a specific match. But let's take your particular case. I would have first looked at the ever helpful ranfft and seeing the Bulova 11DP is based on the Citizen 0241 concentrated on family/generations. You'll know that typically movements in the same family share common parts. Let's go with an 0201 and look at Citizen Movements Parts at CousinsUK. Ah-ha ... a match! And a setting lever spring (assume that's the part you're after) marked as obsolete. But at least we have a part number of 077.05. Look on ebay for 'citizen 077.05' and there's a match ... but given the expense for a little spring we're back round to those donor movements or see if you can use/adapt a spring from another movement.

In my experience, kids have more than enough "springs" in them already. Perhaps a kid spring removal tool might be a big seller.

Ok. I'll join you. But I'll probably get the one with the built in hotplate. That way, if it doesn't work I can use it to a cup of hot cocoa.

If the seconds arbour still intact, use a nail clipper to tighten the mid-section of the tube of seconds hand, you should make sure the tube is mounted on the arbour then press it home. Tube will not find the arbour itself.

Well, who knows, the kids might enjoy them.

Hi Unfortunatly when plastics and rubber denature over time as the oils leech out . I use a plasticiser on my fly lines to recondition the surface PVC maybe that would improve the strap. Its available at fishing tackle store or on line

Time should be passing more slowly if you accelerate, maybe it's just general relativity.

In dynamic state and with associated random high amplitude, hairspring may stick. A video of HS as you manually complement barrel power, would reveal such sticking. Should you set up for vid, I try to capture the guard pin as well.

A: because laws of physics do exist inside of a watch escapement. Vigorous movement will add force to the balance wheel, causing it to store more energy and run faster. The amount of energy stored will depend on the duration of the activity...and that will determine how long it takes for the additional force to be expensed and return back to normal rate. B: nothing you can do its the laws of physics at work.

Well I think that you are right and it is the quartz version...While i know nothing about Omega Seamasters, comparing the full set of pictures on eBay with 'real' ones on the net, it looks to be either the real thing or a very good copy. The only thing that looks slightly different is that the dial loom in the seller's pictures looks very flat compared to this 'real' one... and the end link number '930' appears lazer engraved rather than stamped in, as on this 'real' one....

This is what I can get from my mesurement. Not quite accurate but I hope this will work. The pic is just for demonstration is not the arbor in question.

Hmm, starting at the beginning the winding system (winding pinion, clutch) would need to be remade to work backwards. The stem would need a left hand thread so custom stem and crown. Click would need to be reversed in function, so some machining there. Barrel arbor remade with reverse hook, barrel modified (if not automatic) for reverse hook. The rest of the gear train is ok, up to the escape wheel. This would need to be inverted. The pallet fork could possibly be inverted depending on design (the guard pin needs to change sides at least), possibly remade. That should do it.
