I have one Doxa in my collection.... but it is a lot older than yours... made in 1943. Still a Doxa though...
OP’s watch is very cool - I had to check them out online and came across this review:
‘For me, the Searambler is the weirdest Doxa of them all—less sporty than orange or black, and totally ready for bare chested-Dads of the 1970s.’
This makes me want it even more 😁
