Tudor Black Bay Pro - 39mm 79470 2023 [Preowned]

Overview 

The GMT category runs large: most sport GMT references in steel sit at 40mm and above. At 39mm, the 79470 Black Bay Pro is a deliberate exception; it delivers the GMT function and the tool-watch build in a case size that a specific buyer finds more wearable than the category standard. The fixed 24-hour bezel and Explorer-adjacent dial layout give it a visual identity distinct from rotating bezel GMTs; the orientation is toward precision instrument rather than rotating-bezel legibility.

The case is stainless steel, 39mm, with a fixed bezel carrying 24-hour radial engraving. The dial is matte black with off-white hour markers; the contrast is high and the legibility is direct. The orange GMT hand tracks the second time zone against the fixed 24-hour scale and provides the only colour in an otherwise monochromatic layout. The riveted stainless steel bracelet carries the T-fit clasp with 8mm of tool-free micro-adjustment; at 200-metre water resistance, the build specification sits above what daily use requires, which is where a tool watch should sit.

The MT5652 is Tudor's manufacture GMT calibre, COSC certified and equipped with a silicon balance spring. The GMT function is true rather than modular: the local hour hand jumps independently in one-hour increments without stopping the seconds hand or disturbing the home time on the GMT hand. Power reserve is 70 hours. For a buyer rotating watches across the week, that reserve means the Pro survives a weekend off the wrist without needing resetting on Monday.

Tudor's position in the GMT market is straightforward: COSC manufacture movement, Swiss tool-watch construction, at retail pricing well below the Rolex GMT it nominally competes with. At RM10,500 against an RRP of RM19,830, this preowned example sits nearly 50% below retail for a 2023 piece in excellent condition with full documentation. We are currently seeing Black Bay Pro examples trade at this level; the 39mm true GMT with COSC certification at this price tier has no direct competitor in the secondary market. Preowned, excellent condition, complete with original box and papers dated May 2023, at RM10,500.
