OK, it seems that the weight is the principal problem here.
Thus one more proposal, without the 100 g weight problem:
The Lip Diode reissue of the famous Roger Tallon design - with a leather strap - from mid '70s:
The original may be seen here:

Anyway, the watch design and the orange leather bracelet "screams" '70s and some space age approach on it, especially underlined by the orange "led" display, orange lip marker and the orange leather strap.
And it should/may be under 100 g weight limit, despite of its SS case...
