Rotary GT Monza

This is a queer watch. Rotary is not a well know brand and one of their current model does look like Lecoulte reverso. They're quite an established brand, sadly not a lot of info can be found about them. I have with me an almost new old stock for a diver watch from Rotary. It is an automatic running flawless, the dial is greyish with a screw down crown.
After some research, it appears Jo Siffert wore a similar watch with GT Monza.

Omega Seamaster 300 165-024

wikipedia define diving watch to be "a watch designed for underwater diving that features, as a minimum, a water resistance greater than 10 ATM, the equivalent of 100 meters". Well to me, diving watch is a robust timepeice that tell time in any situation any time, impressed upon others the wearer is responsible for both his and his peers time.
My first dive watch was a vintage Omega seamaster 300 reference 165-024. It has gain much fame after Antiquorum has collaborated with Omega to feature OMEGAMANIA - THEMATIC AUCTION.
It uses the calibre 552, made in the 1960s.
