These 22mm NSA band models are getting so difficult to find. Known as the Silverstone model because it was the original for that famous vintage chronograph watch from the 1970s. Here is a New Old Stock one that is compatible with the 22mm lugs vintage Heuer Silverstone chronograph models and period correct for those watches from the 1970s. This NSA bracelet is the original pattern on vintage Silverstone chronograph watches and was also used as the same links pattern on Monaco chronograph watch vintage models, with different ends. Neither watch is quite right without a matching period 1960s/70s band by NSA Switzerland. This NSA watchband has 18mm wide links at the clasp that flare out to 22mm wide sections. The end pieces are 22mm wide. Restore your vintage chronograph or large vintage dive watch to its original condition with this unique NSA bracelet made in Switzerland. Bracelet is a New Old Stock vintage item from the 1960s/70s and comes in its original NSA box signed with the NSA logo and Novavit S.A. Made in Switzerland. Bracelet is 6 1/4 inches (16mm) long lying flat (extra links are available for purchase). Links are about 2.5mm thick. Comes with the most desirable 2-piece comfort clasp that is spring-loaded and allows the bracelet to open to two pieces to make it easy to put on and take off. Can also come with a standard long flip-locking clasp if you request that type instead. All stainless steel with textured outer rows and smooth center rows. Signed on the back of the clasp "NSA Swiss Made Steel Inox." The clasp "gives" by 1/8 inch as you wear it for perfect comfort. Each link is flexible and removable for micro-adjustment of your size. This bracelet is a rare find that will greatly increase your enjoyment and the value of any watch. Solid steel band that weighs 37 grams. NSA is the brand of high quality Swiss bracelets originally fitted on many major watch brands from the 1960s and '70s. The clasp is interchangeable with the NSA signed clasps if you find a signed NSA clasp later.
