Hamilton Royal Navy Chronograph Tropical.
A bewitching piece of History.
Not mine, but I cannot complain, I have two others which are top nice, too. 
Best,

Beautiful piece of horology! However, IMHO that croc strap is out of place. This chrono would be better on a NATO type strap or similar...
Thoughts on the homage Hamilton recently released?
I personally like it, an attractive form.
It’s slightly larger than the original (40mm vs 39mm) . . .
It’s also quite chunky at 14.35mm thick:
I've always thought nylon NATO straps didn't look right on pre 1970's watches but then a watch account I follow on Instagram featured a UK nylon issue strap still in it's brown paper wrapper dated 1955.
I might get one for my Lemania HS9
Meanwhile, here's a photo of my Timefactors PRS29 AM on a rather nice pale green NATO strap which sets off the dial nicely imho.
Thank you Amanico.
Before anyone says anything, I know the hands are wrong and I do have a correct pair but I like these!
When was the NATO strap introduced?
It can't pre-date NATO but I see them used on WW2 watches.
I wondered if anyone knew the history?

My interest was piqued..
The design dates from the end of WW2 and originally used on survival compasses carried by special forces but made of canvas and then used for watches designated A.F.0210. in 17.5mm. The 6B/2617 was the first nylon NATO strap issued in 1954 for the Mk11 navigator watch, the 6B/346.
The ubiquitous grey nylon NATO strap we see today dates from the 70's.
