The masculinity of a watch depends on the masculinity of the man. A bulky, technical sport watch could look like an over-reach on an arm that could use some time in the gym, but an elegant and dressy watch, styled as this one is for simplicity more than bling, will not undermine the masculinity of an arm that HAS seen time in the gym.
Elegance may be a forgotten trait of masculinity, but it is never really out of style.
