Tropic 21 crystal with cyclops?

[nomad89]

I'm looking for a crystal similar to the Tropic 21 but with a date cyclops at 3. Does anybody know of one like this?

I was looking thru the CousinsUK catalog last week and they have ID's and OD's for the popular Rolex crystals.

T-21: ID: 29.5, OD: 30.6

C-118: ID: 29.4, OD: 30.6

C-135: ID: 29.5, OD; 30.7

So you could try either the 118 or the 135. The 135 fits the 16000 models of Datejusts (3035 movt) and 118 fits the 1600 series of DJ's (1575 movt).

Hi alligoat,

Thanks for that measurement info though!

I tried the Clark's 25-135 but it was a little too tight of a fit once the bezel was in place. And, the cyclops was off centered from the date window. I'll give that C-118 a try. Thanks!

What are you putting this crystal on? Are you building a custom job? I have a crystal for an Air-king date. I cant remember the part # but its about the same size. If i can find it then i will measure it for you.

This is for a custom job using a Swiss V7750.

Air King Date used a Cyclops 117.
