One of the very best NSA Swiss bracelets ever made to carry a large 1970s chronograph or divers watch. Original compatible vintage watch band for something like a big square case Favre-Leuba Bathy Deep Blue or Favre Leuba Sea Sky chronograph. The last link flares out to 28mm wide to make a perfect transition to a large, square 1970s chronograph watch case. Band is shown with 24mm wide ends. You can request the ends to be modified to 20mm or 22mm instead. Buyer selects one size. There are no returns once the width of the ends has been modified at your request. This is the original style NSA watch band compatible with Heuer Montreal Bellof chronograph models and also compatible with Heuer Calculator watches. The peaked shape links are unusual in that they have two stages of links; regular NSA 18mm wide. 2.5mm thick links on either side of the clasp segueing to sections of thick, flared links that are 3.4mm thick. This construction makes the band very comfortable and it provides a perfectly smooth transition to some of the massive 1970s watches that are the most challenging to strap with steel. One of the original NSA Heuer Silverstone bands was built with the wider links sections at the ends like this. Lightly used band made by NSA Novavit SA in Switzerland in the 1960s/70s. Has been ultrasonically cleaned. Length measures 6 1/4 inches (16.2cm), so there is plenty of length for most wrists when paired with a big watch head. The 18mm wide links on either side of the spring-loaded clasp are removable with simple nail-type pins for micro-adjustment for a perfect fit. The clasp is interchangeable with the NSA clasps with logos for many other watch brands. The clasp is spring-loaded so it "gives" a bit as you wear it for perfect comfort. This bracelet is a rare find that will greatly increase the value of any watch. Large 22mm or 24mm lug divers watches just are not the same unless strapped with steel. Solid Stainless Steel link bracelet that weighs 51 grams.
