Case screw for a really nice pocket watch


Recommended Posts

Hi, I am restoring my first pocket watch that has turned out to be a really nice Longines. Unfortunately I have one of the case screws missing and wondered if anyone could help me out with something. I have searched eBay but cannot find anything and I want to avoid buying 100 case screws from Cousins at a high cost when I just need the one. I've attached a little drawing of the screw (1.05 mm across the threads). I can always shorten if too long. Happy to pay something for the screw and someone's time if anyone has one. Thanks in advance.

I'll have a look for you.  Does the dial say Bradford? 

Thank you, yes the dial says J.H. Weeks, Bradford. It did have the remnants of the LONGINES name above the small seconds dial but that is sadly now gone. That's the last time I listen to anyone that says an enamel dial can be cleaned with water. Not to fussed about that though as it still has the LONGINES 19.71 movement inside.

Bradford is my birth city.  Cool.

Deal buster, can't send anything to a lancastrian! Hehe.  Are you sure of the size   seems very large.  I've had a quick look and have some similar, remeasure and I'll send you a selection. 

The screws seem to be either 1 or 1.1mm.

Hi Richard, the size is correct as drawn. 2.7mm head diameter, 4.4mm total length including the head and 1.05mm diameter for the threaded part, including the threads. I'm not proud I will accept a kind offer from a Yorkshire man. If you find one then let me know. Thanks again, Steve.

Let me measure the diameter of the case screw again (the threaded part) and get back to you.

I remeasured and it's definitely 1.05mm.

If anything, the screw feels a bit loose in the hole so a 1.1 mm might possibly fit OK if you don't have. 1.05 mm.

    • nevenbekriev- You nailed it with your description of me and my reaction when the clock started ticking again. I am a newbie.  I love the sound and idea of mechanical clocks but the idea of owning one and trying to keep them running has never appealed to me. My wife bought this one and an antique German wall clock.  When I looked into having someone repair them for me, the universal response was "it's really expensive to work on them, you should just replace the movement". So, I had nothing to lose, I started researching them and opened them up. The wife is happy because she hears the sound of the clocks again. But I have gone down the "accuracy" rabbit hole. In the vertical position, the balance wheel was not floating. It was sitting on the bottom of the frame. I adjusted the lower spring collet and got it floating. It easily passed the 270 degree 3 to 5 minute oscillation test. It took 8 minutes for the wheel to completely stop moving.  I put it the unit back in the movement and checked the safety pin. It does not touch the safety roller anywhere in +/-270 degrees rotation from neutral position. But the amplitude of the rotation with the spring fully wound is weak based on what you are saying. It rotates +/-90 degrees from the neutral position.  No, I did not take the movement completely apart.  That seemed way outside my skill set at the time. There is a reason I became an electrical engineer and not a mechanical engineer. I am much more comfortable with moving electrons than tiny moving metal parts. Will I do it in the long run? Anything can happen. I don't seem to be able to let it go.
    • Isn't that the same guy who told Zelenskyy to escalate the war with Russia/Putin when they already had a peace deal? 2 years later and we have half a million young Ukranian boys dead. He doesn't seem very clever...
    • Thanks guys.  quick question. For automatic movement, particularly this one. can I power down the main spring by pushing this rachet down?  i've gotten pretty used to SW210 and powering down a manual movement. But so far i've only been waiting for the auto movement to run out of juice before opening the case.     
    • @Murks the problem you have mate is most watch cases out there to buy are for Seiko NH3X, ETA 2824 and maybe Myota 8XXX movements, oh also the big ETA 6978/9 movements which the dials start around 28.5mm. You might find one on a Google search but I suspect your main chance will be buying cheap quartz ladies watches and hopefully find one of the right size and condition that is acceptable. 😞   Tom
    • The anchor pin should be perpendicular when the anchor is sat on a flat surface and if you post a close up picture of the backplate I will be able to tell you the correct torsion spring , running fast or slow is usually wrong Torsion spring. Here is a video from my YouTube channel showing how I set the beat
