Which one is fit for it?

The caliber of your watch is the Lemania 1873 so it should be the second one.

Just joined the club of UG crown hoarders 😁



I believe 4 is a saw-tooth style unisonic crown, and 6 is from a polerouter, but the others not sure.Dimensions are written as diameter - depth.

1) 6.13mm - 3.82mm
2) 4.99mm - 2.60mm
3) 5.33mm - 2.73mm
4) 4.37mm - 2.29mm
5) 5.17mm - 3.37mm
6) 4.91mm - 3.06mm
7) 4.48mm - 2.26mm
8) 4.49mm - 2.21mm

You're right on 4 and 6 could potentially be for a Polerouter Super. I have seen several Unisonics with number 2 crowns.

Can someone help me with which size crown I am looking for? I recently got a cushion case model 869126 but it has a replacement crown.
