Mechanical watches are driven by the force of the mainspring as it gradually unwinds. With
an open heart watch you can see the movement of its balance wheel – the beating heart of time – unique to
the mechanical system. The three-dimensional layered construction and detailed case design, ideally suited
to a 40mm watch face, create a sophisticated look of luxury on the wrist.
On the dial side, a small window at 9 o’clock reveals the movement of the balance wheel – the beating
heart of time. The movement has been especially designed for the open heart, where its intricate
dance is on full display.
The peaked, tapered hands glisten beautifully in the light, and the layered dial design creates a
beautiful contrast with its three-dimensional textures.
These details have all been carefully chosen for a 40mm watch face which creates a striking
impression and a sense of luxury.
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.
