SOLLEN SL357 Supercar-Inspired Skeleton Automatic Watch – 43mm, Sapphire, Silicone Strap

SOLLEN SL357 Supercar-Inspired Skeleton Automatic Watch – 43mm, Sapphire, Silicone Strap

The SOLLEN SL357 is a 43mm supercar-inspired skeleton automatic watch — 316L stainless steel case with caliper-style decorative elements on the dial, numbered outer bezel, open mechanical dial exposing the gear train and jewel bearings, sapphire crystal, and a textured contrast-stitch silicone strap. Automatic self-winding and manual winding. 12mm thick, 97g, 3ATM water resistance. Available in silver, rose gold, and blue accent variants.

Key Specifications

Supercar-Inspired Design

The SL357 takes its design language from automotive engineering — specifically the visual vocabulary of supercar internals: calipers, wheel hubs, and exposed mechanical components. The dial uses this reference through caliper-style decorative elements on the left side of the dial face, a large numbered outer bezel with markings at 10, 20, 30, 40, 50, and 60 (echoing a tachometer), and an open skeleton layout that reveals layered gear train elements visible through the case. Purple/violet jewel-tone synthetic ruby bearings provide colour accent points across the movement.

This is a bold, statement-oriented design — the opposite of the minimal CILOA range. It suits buyers who specifically want a watch that communicates mechanical interest and automotive-inspired character rather than understated elegance.

Skeleton Dial

The dial is fully open — movement bridges, gear train, and jewel bearings visible from the front through the sapphire crystal. The layered construction creates depth across multiple visual planes. Luminous hands cross the open mechanical display for low-light readability. The outer numbered bezel adds a sport watch timing reference without a rotating bezel mechanism.

Sapphire Crystal

Sapphire glass — Mohs 9 hardness, scratch-resistant under normal daily wear. The open skeleton dial benefits particularly from sapphire clarity — the quality of the crystal directly affects how much movement detail is readable from the front.

Silicone Strap

Textured black silicone with contrast stitching along both edges. The blue variant uses matching blue stitching; rose gold uses rose-tone stitching. Strap tapers from 27mm at the lug to a standard buckle width. The silicone material is lighter than a metal bracelet and more comfortable during active wear — consistent with the sporty character of the design.

3ATM Water Resistance

Rated 3ATM / 30M — suitable for splash exposure, rain, and handwashing. Not suitable for swimming, hot water, steam, snorkelling, or diving. Keep the crown closed before water contact.

Colour Variants

Silver — brushed silver-tone 316L case with black crown and black/silver silicone strap. The most neutral and versatile variant.

Rose gold — rose-gold tone case accents with matching crown and stitching. Warmer character; the most distinctive of the three.

Blue — silver case with blue bezel accents, blue crown, and blue stitching on the strap. The most sport-oriented colour combination.

How the SL357 Compares in Context

The SL357 sits in a different category from the OUPINKE range — it is a design-first statement watch rather than a precision dress watch. At 43mm and 97g with a silicone strap it wears as a casual sport piece. For buyers who want a skeleton automatic with more horological credentials (named movement, higher water resistance, proven spec), the OUPINKE 3168 and OUPINKE 3178 offer higher spec alternatives.

FAQ

What is the movement in the SL357? An automatic self-winding mechanical movement — self-winds through wrist movement and can also be manually wound via the crown. The specific caliber is not named by SOLLEN. No battery required.

Is the crystal sapphire? Yes — sapphire glass per the specification sheet.

Is it waterproof for swimming? The SL357 is rated 3ATM / 30M, which covers splash exposure and handwashing. Keep the crown fully closed before water contact. Not rated for snorkelling or diving.

What is the caliper design on the dial? Decorative caliper-style elements on the left side of the dial face, referencing automotive brake caliper forms. They are a design feature, not a functional mechanical component.

How heavy is the watch? 97g including the silicone strap — lighter than the OUPINKE tungsten bracelet models despite the larger 43mm case, due to the silicone strap.
