CLASSIC SERIES
Mechanical Open-Heart
The ever-popular Mechanical Open-Heart,
displaying the beating heart of its time-keeping mechanism
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 watch has a slim case which makes it suitable for business use, and it is a popular choice as a pair design for both men and women.

Case made of
stainless steel SUS316L
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. In addition, mechanical models are coated with a single-sided anti-reflective coating.

Size is an important aspect when selecting a watch. Unlike most mechanical watches, which can often be large and heavy, the CAP-38 is small and light, measuring just 38mm in diameter. It is a popular choice for purchase as a matching pair, suitable for both men and women.
The average adult wrist circumference is 16.8cm for men and 15.4cm for women*. Taller people tend to have larger wrist sizes, even if they are slimmer.
