As requested, here are two iphone pics of a Submariner on an Isofrane. I picked up this strap for the NUMA Doxa, but I'm loving it on the Sub. The pics don't do this combo justice (my digital camera is acting up). I'm not asking if this works, I'm telling ya. If you want a comfy, retro, dive strap that actually works with the 'tiny' case/lug gap on a Submariner. . . give this one a try. :-!
