A Watchmaking Standard in a Small Metal Ring

A bezel ring is a metal ring only about 40mm across. It is small, yet it is the first part of the wrist to catch the light. A slight change in material or machining alters the surface grain and the clarity of the markings. PERSLOT builds this small frame like a watch component.

The PERSLOT 316L stainless bezel follows a clear standard at every stage: material, casting, surface treatment and markings. Each difference is small, but on the wrist they add up to one finished result.

1. Why 316L stainless steel

PERSLOT bezel rings use 316L stainless steel. It is a low-carbon stainless grade widely used for watch cases and bracelets. The cool shine and firm feel of the metal remain in the frame.

Once the material is set, the machining standard follows. PERSLOT shapes this steel precisely into a small round ring. Styles with markings and plain styles start from the same material.

2. Superprecision casting for an exact outline

PERSLOT bezels are made with a superprecision casting method, registered as our patent No. 10-1698685. Casting forms a shape by pouring molten metal into a mould. The more precise the mould, the sharper small forms remain, such as numeral edges and outer grooves.

The difference is clearest on designs with dense grooves around the edge. The spacing and depth of each groove must be even for light to break evenly. That is why even a small ring needs the precision of a watch part.

3. Engraving and inking: two ways to mark numerals

Numerals and scale marks are rendered by engraving or inking. Engraving cuts into the metal and shapes each mark with light and shadow. Inking adds colour to the marks for a clearer contrast.

Black numerals on a silver base stay legible even from a distance. PERSLOT offers polished and matte finishes, as well as engraved and inked versions, within the same silver tone. How the markings are rendered sets the character of the frame.

4. A structure that wraps the display edge

The edge of a smartwatch display is more vulnerable than its face. A small knock on the rim can affect the whole screen. PERSLOT designed the bezel to wrap this edge in metal. The structure is made to spread the force of an impact on the corner.

The structure also shapes the design. When metal wraps the display edge, the boundary looks neat. With a black bezel, the screen and frame flow together in one tone.

5. PVD coating and a mirror polish

The surface is finished with PVD coating. PVD applies a thin film to the metal surface inside a vacuum. The even film refines both colour and shine.

A polished plain bezel shows this treatment most clearly. Without markings, the wide metal surface reflects its surroundings directly. Uneven polishing would distort the reflection, so the quality of the finish is easy to notice.

6. A fluted edge and our own production line

A fluted bezel repeats fine vertical grooves around its edge. Each groove meets the light at a different angle, so small highlights travel around the ring.

PERSLOT produces its bezels on our own production line, equipped with advanced machinery used in global watchmaking. Each finished bezel is fixed in a holder and packed in a case. The packaging keeps the surface and edge intact until fitting.

Precision in a small frame makes a watch

316L stainless steel, superprecision casting, PVD coating, engraving and inking. Each is a small difference. On the wrist, they come together as clarity and shine. The more exact the frame, the more a smartwatch feels like a watch.

When choosing a 316L stainless bezel, start with the watch model and size. Then decide on the finish and markings. A PERSLOT bezel puts a watchmaking standard into a small metal ring.
