Collection: Tudor Watch Repair & Servicing in Singapore

How Often Should You Service Your Tudor?

Every 5–7 years for mechanical Tudor watches. The MT5402 is COSC-certified to ±4 sec/day — if your Black Bay is running outside that window, it's a clear sign service is needed. In Singapore's humidity, every 5 years is the safer interval; lubricants degrade faster in tropical conditions. Signs it needs service: drifting accuracy, stiff crown, or the power reserve dropping noticeably below 60 hours.

The MT5402 — Tudor's In-House Calibre

Tudor introduced its first in-house calibre in 2015, ending decades of reliance on ETA movements. The MT5402 powers the Black Bay 41 and Black Bay 58 — it offers a 70-hour power reserve, silicon balance spring (resistant to magnetic fields and corrosion), and is COSC-certified. When you service an MT5402, you're working with a movement that Tudor designed from scratch — different geometry, different tolerances, and different service intervals than the ETA movements that came before it.

Black Bay GMT — How the Movement Works

The Black Bay GMT uses the MT5652 calibre, which adds a 24-hour GMT complication on top of the MT5402 base. The GMT hand advances in one-hour jumps at each hour change, driven by a 24-hour wheel. The local time hour hand is independently adjustable — you set it in one-hour increments without stopping the movement. At service, the GMT mechanism is disassembled separately from the base movement and all components individually cleaned.

Tudor vs. Rolex — Independent Calibres, Shared Heritage

Tudor and Rolex share the same ownership and manufacturing ecosystem, but Tudor's current calibres are independent designs — not rebadged Rolex movements. The MT5402 and its siblings are Tudor-specific movements with their own geometry, spare parts, and service protocol. Our workshop services both Tudor and Rolex separately and correctly for each calibre family.

Independent vs. Authorised Tudor Service

Authorised Tudor service is available but at a significant cost premium and typical turnaround of 3–6 months. For watches under warranty, the authorised centre preserves your coverage. For out-of-warranty Tudor watches, an independent workshop with MT5402 experience delivers professional-standard service at substantially lower cost — with turnaround of 7–18 working days depending on complication.
