predfan2001 Posted April 9, 2008 Report Share Posted April 9, 2008 You guys may remember my old franken-Hydro Tudor....it's long gone but I'm building another. This time I'm going with a cyclops crystal. The case I'll be using will hold at Tropic 19, I've never ordered a cyclops crystal and wanted some verification on which one to order.

alligoat Posted April 9, 2008 Report Share Posted April 9, 2008 CousinsUK has a chart of round special forms plastic topglass in their plastic crystal section- these are SternKreuz crystals. ID of a T-19 is 279, OD is 305. That means 27.9mm and 30.5mm. The T-125 is 295 and 303 so it won't fit the inside ring of a 5513 case. They show a T-127 (for the 1680) but they don't show the ID, OD is 303- so it's close on the OD. Ofrei's has some charts on aftermarket T-19's. The sizes vary somewhat- Lovely... And of course, when you're talking rep cases, who knows what you'll run up against. I do recommend a set of digital calipers for $10-20 from Harbor Freight. Info on Rolex Tropic crystals is hard to come by- it gave me fits on my 5508! Link to comment Share on other sites More sharing options...
predfan2001 Posted April 10, 2008 Author Report Share Posted April 10, 2008 Well the Tropic 127 would be my guess but I just wanted verification. Hell I asked Helfands and got "Can't help you". That's pretty crappy being they ARE a watch parts supplier and I have bought many items from them (but I didn't tell them it was for a rep). Makes me think about buying elsewhere.

Sir-Lancelot Posted April 10, 2008 Report Share Posted April 10, 2008 I doubt the person that answered does know. prolly just an order taker. I had the same experience with Jules Borel and all i asked was for some case clamps for an ETA 2836 cause i cound not find the part number. They told me no case refrence could be found. wtf? If you know exactly what you need and have a part number your all set, if not keep lookin until u find it. lol. Link to comment Share on other sites More sharing options...
alligoat Posted April 11, 2008 Report Share Posted April 11, 2008 A T127 will have the date loupe sit too far on the left. Makes sense, since Rolex dates sit left of the eta dates which is what a Tudor uses- but then I'd suspect that the Tudor case is also slightly different.

predfan2001 Posted April 12, 2008 Author Report Share Posted April 12, 2008 (edited) Movement is a for a Noobmariner (and the date window is aligned with the dial) and the dial fits a vintage rep case.....I'm still guessing T127 Edited April 12, 2008 by predfan2001 Link to comment Share on other sites More sharing options...
