OK, I'll get a little technical...
By movement design, the AutoTractor, which is the dual-time found in the Compressor Hometimes, would be the most robust.
By case design, the Extreme World series, since the case had a shock-absorber system to protect the movement.
Oh, how I wish JLC would re-launch the Compressors in a 42mm or 43mm design with the strap change system. The Compressor Geographic on bracelet is one of my all-time favorite JLCs.

I'm with Nico, I would say the Extreme Lab 1 and 2 followed by the Navy Seals line and Compressor lines 😉👍
I have an Extreme Lab 2 Ti and a Navy Seals Alarm, both of which I have worn through anything and everything from extreme sports to sky diving, etc...They never skipped a beat 😉👍
TiVan15
Agree with the above. Side note, the EL2 case was made of something JLC calls TiVan15 which I assume is marketing for a 15% vanadium titanium alloy. Typically these high vanadium content titanium alloys are significantly harder and stronger than grade 5 t...

Here is the original article from 2004...
The pictures don't seem to load easily, if at all, but the info is great on the development of the movement. www.watchprosite.com -Dean
The extreme lab series cases seemed one iteration further developed than the extreme world watches
The extreme lab 1 & 2 fully encircled the inner case with the outer case vs extreme world series left the inner case partially exposed on the sides. Further, the extreme world cases were stainless and titanium vs the extreme lab cases in titanium and carb...
Agreed. The Extreme Lab series was and is JLC's most technically advanced watches in terms of durability, resistance, materials, etc...The autotractor movement inside the Compressor series has already super robust but the Extreme Lab series...
and the movements used took it to another level. I still hope JLC will reintroduce or make an Extreme Lab 3 as I would be queuing in line for one if necessary 😉👍
