So, I was smart and lost a screw for the back cover of my watch. I still have the other ones and I am unsure how to identify them to get some replacements.

The obvious places like eBay, Amazon all sell screws for similar models but I could not find anything for mine.

From what I can tell it is a Y0 head and without measuring, just from reading online it seems it is 3.5mm long.

Now with that, I know there are different thread sizes, etc. How would one go about determining all of that.
All without costing more than the value of the watch.

Do watch repair places usually carry an array of screws and they might just have what I need?

If not, how could I determine if the screws of a newer model watch would fit?
I see Samsung at least stuck to the Y0 head. But I assume that does NOT determine the diameter of the screw? Or the thread size?

But then again, from a business perspective, why change it for no reason? Same part, less cost!

Anyways, I was hoping someone here might be able to guide me in the right direction.

 

Thanks!

    • Thank you @Mark. I only became a Patreon subscriber 5 or 6 months ago, but I draw so much value here. If you come up with future contribution or support opportunities, I will be on board.
    • Hi Mike I did a ships clock a long while ago, not a Hermle though and without getting the beast in my hands to refresh my memory I can’t recall the timing.  This doesn’t help I know but will start the grey matter turning.
    • Of course it will continue Richard.
    • I have stripped and cleaned a Hermle ships clock. It was just oily, no major faults, and I reassembled it, following my photos in reverse order. The time train is fine but the strike train will not play the ships bell strike for half-past. Ships bells play a four hour sequence for the 'watches' and play double 'ding' for the hour and the double dings plus one for the half past (eg half past the second hour is 'ding-ding' 'ding-ding' 'ding'). Sounds complicated but it isn't really. The strike wheel consists of pairs of bumps (for the ding-ding) and no single bumps. There must me some mechanism on the half-past that lifts the strike lever over one of the bumps so only one ding is played. When I get to a half past, it still plays double ding. I have a feeling it is to do with the lever in front of the rack (there is a sprung attachment  on it) and the position of the wheel (to the right) with the two pins that lets that lever fall, but no matter where I place that wheel I cannot get a single ding at half past! Please can someone help with advice on positioning so I can fix this? BTW Happy Easter 🐣
