Elgin ELGIN Jumping Hour This is a golf ball iron mask. The Lord Elgin became famous because Elvis Presley used a jumping hour watch, but the rarity of the round iron mask is compounded by the fact that golf ball collectors don't let go of them, so they are not often seen on the market. The well-balanced, small case, though American-made, fits Japanese wrists, which seems to be a particularly rare reason. The rectangular Tenderloin has a lug width of 19mm, while the golf ball round has a lug width of 16mm. As it is called a golf ball, it has an exquisite dot finish, giving it an elegant design. The case back says 10K RGP BEZER, so it's a hooded case with an integrated bezel, meaning the entire case top is 10K plate.
