the Worlds first speedometer wristwatch introduced on the Watch Basle Fairs in 1974 or 1975.
Derby Swissonic - available as Jaz on some European markets.
Fitted with a Swiss ESA 7 jewel movement with electromagnetic balance.
Jumps every minute and every hour so this watch should really be called Jumpminute :)
this piece is in excellent condition and fully functional guarranteed by me - the Derby Expert :)
these watches are known for not being reliable after so many years so you can look further for a bargain that will not be repairable or buy from me.
available with 28mm wide leather straps - black, orange or vanilla.
sorry, that's even below eBay prices not to mention that this one is guaranteed 1000% for perfect setting and timekeeping as opposed to eBay Derby watches. finding a perfect working Derby is not easy, unless you just want a display watch.
