TPH Depthguard 300 — 42MM Handcrafted Mechanical Timepiece
The TPH Depthguard 300 is a handcrafted mechanical watch shaped by a heritage of artisan watchmaking and built to order in the TPH atelier. Each example begins at the watchmaker’s bench, where the 904L stainless steel case and its matching bezel are finished by hand — brushed, polished and inspected through every stage to achieve the deep, balanced lustre that distinguishes TPH metalwork.
Sealed beneath a black sapphire crystal, the black dial is assembled entirely by hand. Applied stick and dot hour markers and the signature sword hands are milled from 904L stainless steel and individually set for flawless alignment and legibility.
Mechanical Movement
At its heart beats a high-quality automatic mechanical movement, calibre 8800, regulated by hand in the TPH workshop. It offers a generous 60-hour power reserve and a precision of -3/+3 seconds per day, held within COSC chronometric limits. Every component is decorated, assembled and timed by TPH artisans before the case back is closed and the timepiece is signed off.
Artisan Craftsmanship and Custom Design
The Depthguard 300 is never a mass-produced object. Each watch is a custom creation, assembled to order from a choice of finishes, marker styles, hands and strap combinations. TPH welcomes bespoke commissions — caseback engraving, bespoke dial finishing, and tailored bracelet configurations — so that every Depthguard becomes a personal expression of its owner.
Wearability
Presented on a black rubber bracelet with adjustable links, the Depthguard 300 sits securely and comfortably on the wrist, with water resistance rated to 30 metres.
