Haylou Watches 44mm & Larger

4 Haylou models in the 44mm and up range, actually measuring 45.2mm to 45.7mm. Bold, high-presence sizing best on larger wrists.

Thickness barely moves across the group — 11.4mm to 12.4mm — so these wear much alike under a cuff.

3 are round and 1 rectangular — at the same nominal width, a rectangular case covers noticeably more wrist.
