sorts of adjustments until I can get a watch to feel just right, the same as you did with your Rolex. The 3700 does not have the adjustable "fitting clasp" as your Rolex so you don't have the capability of getting close and then adjusting the clasp by moving a springbar for exact fitting.
The 3700 has the blade style folding clasp which is different from the double folding clasp seen on the later Nautilus models. That can affect fitting as the position of the blade on the inside of your wrist may feel uncomfortable. I currently have a 3800 which has the newer single blade style folding clasp and ended up buying a " 1 1/2" link which allowed for the watch to not only be the right length but also the perfect position of the clasp. Check and see if a "1 1/2" link is available for the 3700 and if so, I believe you will be able to have it fit you correctly.
I have a 3710 here with the double folding buckle and there are plenty of links to remove to get close to a proper fit but would suspect I would nee the "1 1/2" link to get it perfect or at the very least close to perfect.
Hope this helps.
