Here's a drawing just to clarify what I mean. (I'm assuming that all nominal "36 mm" cases are the same 35.5 mm measurement across the case?) Surely knowing these dimensions would help one make decisions about donor cases or reps? I did find one reference online to the 1016 being "35 mm x 45 mm". So there, subject to interpretation, is one data point.

Alligoat--thanks for the welcome! Yes I've been reading and re-reading LH's posts since I found this forum, I have also been doing my best to wear him out with questions and blather via PM as well. This forum is an awesome resource no doubt. LH--yes I have seen that 16000 thread, in fact it has been staring at your comparison picture that led me to want measurements to confirm or correct my impression that there are differences in the lug geometry. Automatico--thanks for the crown/tube info!

Seems like the lug geometry on the usual candidate gen cases may be different? Can anyone provide dimensions for a 1016 (and other gen Explorer cases for that matter) and the 1601, 16000 series and 162XX? Also any dimensions for common rep cases would be great. Aside from knowing the long dimension and the case thickness it would be interesting to know the overall height of the case without the back, and the distance between the lugholes along the case. I know making a donor choice is a lot about matching style and shape (been reading and re-reading the relevant threads), but I'd like to put those choices into a clear-cut framework if I can. Also do these differences affect what end links are needed? Might one for instance need to replace the end links on a Yuki 7206 to make it fit well to a 16000?

Okay I just have to come out of lurk and drool publicly over this watch. I've been studying-studying over the last week trying to get a handle on what options there are for a satisfactory early Explorer rep. JMB's recent products have been at the top of my radar over the last few days and I nearly sent him a PM yesterday but held back because I know I still have a ton to learn. Must-wait-till-not-ignorant.... Seeing this one makes me very impatient to get going. Many thanks to all who have posted about these over the years, the info here is very helpful if a bit overwhelming for a newbie trying to learn it all in an instant.
