RM Tonneau Automatic — 42mm Barrel Case by Wclocks
A Wclocks original. The tonneau barrel case is one of watchmaking's most sculptural shapes, and this 42mm automatic wears it in six distinct colourways — including Black Carbon and Rose Gold. Wide 25mm silicone strap. Numberless dial. 5 ATM water resistance.
Key Specifications
What Makes It
Tonneau Barrel Case
The curved barrel shape curves at the lugs and sides simultaneously — a case geometry that requires more complex machining than a standard round or square case. Immediately distinctive on the wrist.
Automatic Movement
Self-winding mechanical movement keeps this running without a battery. Wind it by wearing it, or manually via the crown after a few days off the wrist.
Numberless Dial
No numerals — just hands on a clean surface. The tonneau case does the visual work; the dial stays minimal. Hours and minutes read from proportions and position alone.
Six Colourways
Red, White, Steel, Black Carbon, Black, and Rose Gold. Each one reads as a distinct watch rather than a variation on the same theme.
Most watch cases are round. A few are square. The tonneau — a barrel shape that curves simultaneously at the top, bottom, and sides — is genuinely uncommon, and it is uncommon because it is harder to make and harder to execute well. When it works, it creates a wrist presence that rounds and squares simply cannot replicate. The RM Tonneau Automatic is a Wclocks original in that case shape: 42mm, 15mm, automatic movement, wide 25mm silicone strap, numberless dial, and six colourways designed to exploit the sculptural quality of the tonneau form.
Black Carbon gives the case a composite texture — the most technically aggressive of the six. Rose Gold is the warmest and most wearable across different clothing combinations. Red is bold and unambiguous. Steel is the purist's choice. White is the most graphic. Black is the most versatile. All six share the same movement, dimensions, and water resistance — the only question is which mood you want on your wrist.
