I have for sale two different rubber b straps made specifically for the Rolex deepsea sea dweller. Both are barely used so save some money, prices includes priority shipping (usually 2-3 days). I will outline the details, prices and pictures below. First up is the black strap with recessed white stipe item number M107-VCWT, excellent shape with the original package and insert as seen. These are $280 new, I will take $225 including priority shipping. Here are some pictures: -------------------------------------------- Up next is the all black style made to be used with your factory clasp, item number M108-S. Again, it is barely used and includes the original packaging as seen below. These are $250 new, I will take $200 including Priority shipping. Here are some pictures: Thanks for looking. I have plenty of references here, on the Rolex forum, watchuseek and of course eBay.
I neglected to say the 108-S, if you look at their size chart it is actually a size 5/7. I got that size because I wanted to remove my divers extension but this size might work for you whether or not you removed your divers extension. It is, as the size implies, equivalent to 5 links on one side and 7 on the other.
The M108-S is sold. I still have the M107-VCWT for sale, the one with the buckle included. New they are $280, I am asking $225 shipped. This is the one I still have for sale:
