Trench Siren

ONLY 1 LEFT IN STOCK! 

True to its name, the Trench Siren carries a dial that feels like a call from the deep, rings of vivid colour radiating outward in orange, green, and blue. The luminous hands move through this signal with quiet precision, anchored by a steel case that keeps the watch grounded and resilient. It’s a piece for those drawn to bold colour, clarity, and a presence that speaks without raising its voice.

Featuring Waterproof sailcloth style nylon hybrid material strap, a polished silver buckle, and quality stainless steel quick‑release pins for simple, tool‑free changes.

Each Trench Siren is delivered in a signature Sanctum leather case, designed for long‑term protection and understated presentation.
