Shear is generally reliable, but not infallible. I have never seen an original 1016 without the SCOC & SWISS - T < 25 on the dial. But, as is often the case with vintage Rolex, never say never.
Running the latest version of Firefox, I am getting the error if I try to Edit a post I just posted. Once I am in the Editor, the system will not allow me to do anything (including go to the Full Editor or Cancel), instead returning the same error as noted above.

Why not just buy a good rep (research the gen you are interested & then peruse the RWG dealer listings for the version YOU like best), which, in the case of an Explorer, is pretty close to 90% correct out of the box.
fyi - the 5500 came with either a 1520 or 1530 movement, 6635 or 7205 bracelet (both with 57 end links), a 5.3 Twinlock crown/tube & a Tropic 11 crystal
These inserts will fit a gen bezel without modifications to either the insert or the bezel. So it should also fit any aftermarket bezel made to gen specs.
Looks great so far. If you look inside the new tube, you should see some splines
There is a tool/wrench that fit into the splines & is used to screw the tube into the case
If the replacement movement (sent by the original seller) is wrong, I would send the whole thing back for refund. Then, get 1 of the ETA-powered versions--either correct hand stack (chs) or incorrect hand stack (ichs)--from an RWG listed seller.
If the (gen) hands are original to a (gen) watch, then the lume should match. A Mismatch generally indicates that either the hands or dial are not oem.
To my eye, the relative height of the crystal (above the plane of the bezel) is always the give-away. If you are fortunate to have 1 of the low-profile rep cases, the difference is minimal & it is doubtful that the average gen owner or collector could ID it as a rep without close inspection. And, even then, it may pass
Always best to phone Ofrei for info or to place an order with a part number (unless you ask for him, you are unlikely to speak with Bob). Here is a summary of the most salient rules regarding emails to Ofrei -
Gen is definitely on the left. By-Tor wrote the definitive review of the 116520 & the dials have been top-notch for quite some time (to the point where I have twice refused amazing deals on gen dials because they were not sufficiently better than my rep's to warrant the time it would take to swap them ). Unfortunately, they have a way to go on their cases.
Depends on which crown is fitted & the condition of the crystal & seals, but I believe Rolex sports watches, unless otherwise specified, are spec'd to 100m.
