watchguyusa1 Posted May 26, 2016 Report Share Posted May 26, 2016 Im having problem finding a T127 crystal for my 1680 build that the cyclops is lined up over the date window? its way too far to the right! I have to tilt the watch to the left to read the date? I know the right cyclops position exist as Ive seen 1680's with them, is it only a GEN 127 that will give me the correct position? does anyone here had this issue before?

automatico Posted May 27, 2016 Report Share Posted May 27, 2016 I use aftmkt 127 crystals from different suppliers and they have been Ok. I have two '1680 Frankenstein' watches, one with a genuine dial and 1570/75 and one with a Yuki dial and 1570/75. Both have aftmkt crystals and both line up over the date correctly with good magnification. Trouble can arise when an Eta movement and 'Eta specific' dial are used with the date window not in the correct (oem rolex) location and the date wheel made to match...this will make the date too far to the right. The fix calls for an 'open 6/9' date wheel overlay and rolex spec dial...or a crystal without a magnifier. Otoh, if the magnifier on the crystal is too far to the right and your dial/dw are 'oem rolex specific'...you may have a oem spec dial/dw combo and 'Eta specific' crystal. Whew! Most of the oem spec aftmkt crystals are pretty good when they are from well known supply houses and I have always had good luck with GS brand crystals. The rolex crystal p/n is 25-127 but if it was me, I would not spend the $$ on one for a project watch. Link to comment Share on other sites More sharing options...
watchguyusa1 Posted May 27, 2016 Author Report Share Posted May 27, 2016 Thanks! I have the date window in the correct Rolex position, the Cyclops is too far to the right of the date window ,so you have had the GS brand 127 and the Cyclops was in the correct position?

marrickvilleboy Posted May 27, 2016 Report Share Posted May 27, 2016 post a pic and we can give you better advice. Its uncommon for the generic suppliers to provide wrong cyclop positions, especially if you have tried several different suppliers. Its more likely your dial isn't gen-spec.

Nanuq Posted May 27, 2016 Report Share Posted May 27, 2016 I've used a Clarks 127 on the Nastymariner and the cyclops position is dead on. Link to comment Share on other sites More sharing options...
alligoat Posted May 27, 2016 Report Share Posted May 27, 2016 Ofrei has a Sternkruz crystal- you can see where the cyclops is closer to the center than on the 125 which is for a Tudor eta http://www.ofrei.com/page419.html XS 303.430 Link to comment Share on other sites More sharing options...
hugop Posted May 29, 2016 Report Share Posted May 29, 2016 I also use the Clark 127. Here is one on my MBW 1680. 1 Link to comment Share on other sites More sharing options...

The Sternkruz XS 303.430 has the correct cyclops position right over the date window and the magnification looks DEAD ON when compared to the gen 1680 pics that I could find, I also ordered the Clarks and it was way too far to the right, so maybe you guys who got ones from Clark that were good maybe from a different batch?

automatico Posted June 8, 2016 Report Share Posted June 8, 2016 The Clark crystals might be good for watches with genspec case necks/bezels and Eta date offset. Link to comment Share on other sites More sharing options...

Yes the Clark will be perfect for that type of build for sure! Link to comment Share on other sites More sharing options...
Mendota Explorer Posted June 9, 2016 Report Share Posted June 9, 2016 Would the Sternkreuz work with the PT 1680 or would I need the Clark for that? Sent from my SM-N920P using Tapatalk Link to comment Share on other sites More sharing options...
Mendota Explorer Posted June 9, 2016 Report Share Posted June 9, 2016 I only ask because while I really like the T19 with these, I'd also be interested in having a better T127 option than the stock one. My stock top hat is getting scratched and dinged now. Sent from my SM-N920P using Tapatalk Link to comment Share on other sites More sharing options...
Drummania Posted June 4, 2017 Report Share Posted June 4, 2017 Sorry for digging up this thread. I have JKF (cartel) 1680 and the Sternkreuz xs 303.430 crystal. The look of the crystal is perfect but for some reason it is a bit loose on the case. Did you have this problem?
