At least that is the idea and that is what the JLC marketing want us to believe.

Logically, if JLC were to make an Extreme LAB 3, it should also be designed for another type of harsh environment. What comes to mind is a super dive watch, with crazy depth rating and a mechanical depth gauge that can be used for the entire depth range. It should have unusual complications for a dive watch, such as a tide graph or even sun rise and sun set. I would love to see JLC takes on the equally extreme Blancpain X fathom.
Another option is for JLC to design a modern mechanical space/ moon/ Mars watch. Tough enough to survive all the shocks and extreme temperature differences, yet provide unthinkable complications such as a star chart that can be set anywhere in or outside of the world.
As for the case size and costs. I donโt think an Extreme LAB watch should be limited by these arbitrary factors. Let the design team runs wild, let form follow functions, let them have an unlimited R&D budget and see what they are capable of. This is what I would like to see for the next Extreme LAB watch. I can dream....
Best,
