93150 Bracelet Screws. 2 Types?
I just removed a link from the 6 o’clock side of my 93150 bracelet from my 14060M (Y 2002). I did a pretty good job at not messing up the screw for the most part. I did purchase a hollow ground screwdriver but the tip crumbled so it’s not useable anymore. Kinda disappointed about that considering it was a reputable screwdriver from a reputable tool dealer. Anyways...
When I run my finger over the screw on the flat side (the one without the slot in it) it is ever so slightly raised above the link. And I mean ever so slightly. Most non-OCD people would not even notice, lol! It’s the first screw that connects the clasp link to the removable links (red line in the attached pic). I realize that from the factory they polish the link and screw when it is already together so that they are perfectly flush and have the same luster. So I could always have an AD polish it down. But... I was looking at the attached bracelet reference guide and was wondering if someone could help verify for me the difference between the 2 screws I’ve identified (with the red box around them). One shows 1.40mm (32-20687) and the other 1.70mm (32-20688). I wonder if the screw I used was the wrong screw when I re-attached the links? Maybe I mismatched the screws or something? Or is there just one type of screw of the two in the pic used for the links? I cannot figure out the difference. Any help would be appreciated. ![]() |

I ended up backing the screw out a hair, which seems to have resolved the issue. Must have over torqued it a bit. But still curious to know the difference between the 2 screws in the pic? Anyone know?

Thanks for clarifying Peter. But I still don’t know the difference between the 2 screws on a 93150 though. Any insight? One is 1.70mm and the other is 1.40mm. Where do each of these go? Do you happen to have a diagram similar to the one you referenced, but for a 93150 by chance?

93150 Screws
Hi Everyone, I went into this dilemma and here is the answer:
When the 93150 bracelet was introduced in 1975 it used 32-20688 screws these are 1.7 mm in diam. shank and threads. Sometime in the 80's Rolex switched to 32-20687 screws which have same 1.7 mm diam. shank but 1.4 mm diam. threads. If you have an early 93150 from the 70's you need the 32-20688 screws if you have a modern 93150 from the 90's you need the more common now 32-20687 screws. If you have a bracelet from the 80's it is better to take out one screw and measure the thread diam or simply look if the threads are clearly slimmer than the shank or are of same diameter. The original screws maybe hard to find but Rolliworks said manufacture their own at least for the new models and these should be better than unknown types in the market. Hope this helps. |
