The late Jonathan found this OEM crystal for me, which took him months, and then he installed it for me as well.
Actually, the original bracelet was too short, and Jonathan fitted another bracelet for me. Note that the lug-ends are really different from regular lugs. He retained the original clasp as well. I really miss the days when he was still around.
The reason for the mod is that original dial went through some water damage. It looked "spotted" with such wonderful crystal, to a degree that I can't stand it. So the mod. Some on the forum suspects that if quickset tooth is broken so the mod. No. The gear is still fine, but I really don't need day/date window with this watch.
