Replacing crystal on 198.003 - differences between 5106 variants?

[powasky]

Hey folks,

First things first - this forum is a wealth of knowledge that I deeply appreciate. I've searched it many times as a non-member, and finally came across a question I can't search up the answer to.

Based on the research I've done, my stainless 198.003 takes a 5106 crystal. In searching the net, I've come across a couple variations of the 5106:

- PZ5106 is the 5106 with a silver tension ring
- PX5106 is the 5016 with a gold tension ring

an "L" on the end indicates a magnifier.

Am I correct in assuming that the PZ5106 is the correct crystal for this watch?

I looked on the extranet, there is also a rose gold tension ring variant:
063PY5106 | GLASS PLEXI 5N RING D31.62 H4.15



It does look like all steel case variants of this watch use this for a non-magnifier crystal:
063PZ5106 | GLASS PLEXI ST RING D31.62 H4.1

For...

STEEL CASE CAL. 1250 | 055ST1980003

The two crystals listed are:

063PZ5106 and 063PZ5106L.

So both magnifier and plain crystals are used.

I appreciate your insight here!
