Aha! The power of good record-keeping.
I believe that the 93253 bracelet to which you refer was first fitted to 16613s in the late "Axxxxxx" series of watches.
Solid lugs (denoted by the suffix "T" between the lugs i.e. "16613 T") did not appear on the 16613s until the high "Yxxxxxx" series.
This creates a surprisingly large period where the solid end link 93253 bracelet was fitted to the open lug cases, from late A cases through P, K and most of the Y series.
The date codes on clasps can be confusing, as they do not correspond with the prefixes on the main cases. The earliest clasp code I have on record for a 93253 is "X12" which suggests manufacture in December 1999.
What geek?
