Simple, slimmer 38mm and
luxurious, larger 40mm

There are two mechanical open heart models from Knot: the simple, slimmer CAP-38 especially suitable for daintier wrists, and the CAP-40 with its layered dial design, varied textures and larger lug case, making for a more pronounced appearance on the wrist.

A prominent lug case made from
SUS316L stainless steel

The prominent lug design is an exceptional match for the 40mm case size. Knot uses SUS316L – a high-purity, corrosion-resistant, stainless steel used for medical scalpels – as standard. This material is pleasing to wear even for those with metal allergies, as it produces almost no metal ions.

※This does not exclude the possibility that an allergic reaction could still be experienced by some people.

Sapphire glass

Sapphire glass crystal is made of the same composition as sapphire gemstone. All Knot watches are created using scratch-resistant sapphire glass which measures 9 on the Mohs Hardness Scale, second only to diamond which is rated 10.
