By TLex Aquadive is now offering a new case back for the Model 77. The new casebacks are 2mm thinner than the original vintage NOS caseback; immensely improving the wear-ability of the watch. As the Model 77 case is curved, it combines with the new thinner case back, helping the watch hug the wrist much better.
The new caseback wasn't offered at the ORIGINAL launch in order not to alter the originality of this vintage model. However the new case will be offered on an optional basis. Current owners of the Model 77 can send in their watch for an upgrade for a fixed rate of 89USD + 10USD shipping. New customers can also order the watch with either the original, or the new thinner, caseback. To order your upgrade, please visit Aquadive's online STORE.
