    Technically, these watches are uni-compax. Other variations are compax (three subdials) and tri-compax (four subdials).

    Just saying...

    Isn’t it the number of complications, so chronograph with date is bi-compax?

    There's no such thing as bi-compax in the classic compax terminology. Yes, I've seen definitions that simply refer to complications but so for as I'm concerned correct use of the terms should be in respect of subdials.

    Some may argue with me, but take this as an example - a tri-compax. Four subdials but there are eight complications in total (in fact, one of the subdials has two complications). It's a tri-compax because it has four subdials.

    For example, here's a tri-compax. Four subdials plus additional complications that are ignored for these purposes.

    Interesting, though presumably a bi-compax could be dreamed up that fitted your definition.

    I think the correct term is two register.

    Here's my Top Time from 1965.

    I've actually amended the view expressed in my earlier post for clarity (sorry). Yes, you can dream up anything you like, I was just referring to the classic (i.e. UG's own) nomenclature.

    My Heuer 1550 SG is the only one I have. The UG and Prs5 ^^^ look great.

    Two registers, bi-compax, or something...

    It seems I'm a sucker for a two register chrono!

    Panerai PAM654. I tend to prefer no complications (excepting my Equation of Time) but this one just looks so right.
