Time to revisit the Revisited thread... with strap options! I've long been trying to find out which metal bracelets were used on the Fifty Fathoms back in the 50s and 60s. I've had this ad in my Blancpain picture archive for a while:
Looks like your standard expansion band bracelet, which was strangely popular at the time. Finding a match was harder than expected, especially since the genuine vintage FFs had lug spacings of 19-20mm (rather than the DSN rep's 22mm). There were good matches on eBay by NSA and J.B. Champion. Unfortunately, these were selling for around $80, so I decided to go cheap and "close enough" with a good ol' Speidel:
And by "good ol' Speidel" I mean "good ol' ill-fitting, hair-tugging, rattly, chintzy Speidel aka 'The Depilator'". You probably won't be seeing this bracelet ever again!
Next up is a vintage "Tropic-style" 22mm rubber strap that I recently bought for peanuts. The strap is soft, flexible, and in far better shape than the oxidized rubber on my Tropic (pictured in the OP). Other than the keepers, the strap is a good match for a real Tropic. It's either a "Hong Kong Tropic" (manufactured in the 1980s, I think) or a Voguestrap Skindiver (which might be the same thing).
Curved ends look good!
In the end, I have to agree with redwatch. The look that gets the most attention isn't from the 50s or the 60s, but from that shark-hunting, disco-dancing decade: It's the 1970s, and it's got to be mesh.
