Oversized Reinvented

Through a successful crowdfunding campaign called The XL Watch Project, Terranaut created a collection of oversized watches that offer a more comfortable fit – the XL 50MM.

The extra-large watch case is ergonomically curved so the weight of the watch is evenly distributed around the wrist.

The unique method of attaching the strap directly to the underside of the case makes it feel smaller to wear.

Terranaut watches are manufactured from a blend of premium materials, including aerospace-grade 316L stainless steel, top grain leather and carbon fiber.

Final assembly is completed in the United Kingdom.

Destined to become a collector's item, every Terranaut XL 50MM watch is a limited edition.

It’s time for you to be noticed. Be bold and choose bigger.
