“A little smaller than it seems. Case is 42mm but with the tapered cone shaped, it actually looks much smaller. Thin band as well. Almost the size of women's watch. It's my fault I didn't look closer at the strap size. That would have given me a better idea. But in my mind it seemed larger. It's definitely the flared out edges at the base of the case. But all in all.. Fantastic movement and a joy to "watch"!”
