Hi, I have a vintage oblong Seiko. It is only 33mm 24mm x 5mm. I have fitted a hand made Ostrich leather strap, which came with a standard tang buckle. I would like to put a deployant clasp on the strap but do not want the clasp looking bulky. I have small wrists and have researched double and single fold clasps to see which would be better. It seems single is best for small wrists. Most clasps appear bulky on the wrist but I cant be the only guy that is after a thin clasp to compliment a dress watch. I would very much appreciate knowing whether anyone has found a suitable small and thin clasp. thanks jack.
