STS-38 / STS-32
SUSTINO series

Thin Solar

Thin, lightweight, next-generation solar.

The first watch in Knot’s new SUSTINO series, created for the bright future that awaits. It features a sleek, cutting-edge case design which sets it apart from the standard models in the Classic series and the weightier Premium series.
The watch’s case is just 6mm in thickness, with the 38mm model weighing 24.7g while the 32mm model is a remarkable 18.5g.
Knot’s 36mm flagship model, the CS-36, has a weight of 25g, but the larger 38mm SUSTINO manages to weigh even less. Meanwhile, the 32mm SUSTINO model is Knot’s lightest achievement yet. Its thin and lightweight profile make it exceedingly comfortable to wear, barely perceptible on the wrist.

Product list

Solid industrial design with nothing superfluous

The solar movement powers the watch with sunlight, eliminating the need for battery replacement and reducing battery waste compared to quartz models.
The case has been reduced to a bare minimum to achieve a thin, light, comfortable fit, leaving no extra weight to carry around. The watch exterior embodies the concept of sustainability, and is an expression of our goal to create a design with the lowest possible environmental impact.

Knot’s first design pair

For the first time, Knot is releasing a watch design in two sizes. The SUSTINO’s neutral appearance means both sizes are suitable for men and women, and the two sizes can also be recommended as a pair: a 38mm watch for strong wrists and a 32mm twin for slender wrists.

Mathematically angled ring
for optimum exposure to sunlight

The angle of the watch’s reflective ring has been carefully calculated to focus light on the solar cells beneath the dial, and integrated hour and minute markers add to the overall futuristic look. The dial plate has a simple face, comprising only the logo and ensign. The markers are subtle and sleek. Their polished finish creates a contrast with the ring’s matte texture, ensuring legibility while retaining a minimalist appearance.

A beautiful dial plate
with both form and function

The solar movement utilizes the MIYOTA EL31. We have created a resin dial plate with a high-quality finish and excellent light transmission, concealing the solar cells while retaining optimum light transmissibility. The dial plate’s metal-like texture is so refined in appearance that it is hard to believe it is constructed from resin.

An appealing case back,
ready for engraving

The case back features the Kichijoji wave pattern – an endless succession of gentle waves expressing a wish for a future world of peace, harmony and sustainability. Naturally, the case back can also accommodate engraving.
