ZF Factory Tudor Black Bay M7939 Red Automatic Watch
The ZF Factory Tudor Black Bay M7939 combines compact vintage-inspired proportions with a distinctive red color scheme. It features a 39mm stainless steel case, red anodized aluminum bezel, domed red dial, luminous snowflake-style hands and a 2824 automatic mechanical movement.
Its relatively slim profile and adjustable bracelet make it suitable for daily wear, business-casual clothing and vintage-inspired watch collections.
39mm Stainless Steel Case
The watch features a 39mm stainless steel case with an approximate thickness of 11.7mm.
The compact dimensions provide a comfortable fit without creating excessive bulk on the wrist. Brushed finishing is applied across the upper surfaces, while polished case sides and bevels create contrast around the profile.
A large screw-down crown with a raised rose-style emblem complements the vintage-inspired appearance and provides a secure grip during winding and time adjustment.
Red Anodized Aluminum Bezel
The bidirectional rotating bezel features a red anodized aluminum insert.
Its deep red tone complements the matching dial while adding a distinctive visual identity to the watch. Anodized aluminum is lightweight and corrosion resistant, making it suitable for a vintage-style sports-watch bezel.
The bezel should still be protected from strong impacts and abrasive surfaces, which may affect its finish over time.
Domed Red Dial
The watch uses a domed red dial that creates subtle changes in depth and reflection under different lighting conditions.
Gold-tone applied hour markers add warmth to the red surface and reinforce the vintage-inspired color combination. The clean layout keeps the display easy to read while maintaining a balanced appearance.
Snowflake-Style Hands and Luminous Display
The dial is fitted with signature snowflake-style hands and applied hour markers filled with Super-LumiNova®-style luminous material.
The broad hour hand, clear minute hand and luminous markers provide strong contrast against the red dial, improving readability during both daytime and low-light use.
Rivet-Style Three-Link Bracelet
One available configuration includes a stainless steel three-link bracelet with decorative rivet-style side details.
The bracelet combines brushed and polished finishes, while solid links provide a substantial feel. Smoothly finished edges allow the bracelet to sit comfortably against the wrist.
Five-Link Bracelet Option
A five-link stainless steel bracelet is also available for users who prefer a more flexible and refined wearing style.
The smaller individual links allow the bracelet to follow the wrist more closely, while the alternating finishes complement the polished and brushed surfaces of the case.
Specific bracelet availability should be confirmed before ordering.
T-Fit Style Adjustable Clasp
The bracelet is equipped with a T-Fit style micro-adjustment clasp.
The tool-free adjustment system makes it easier to refine the bracelet fit throughout the day, especially when wrist size changes slightly because of temperature or activity.
2824 Automatic Movement
The watch is powered by a 2824 automatic mechanical movement.
Normal wrist movement helps maintain the power reserve during regular wear. If the watch has not been worn for an extended period, it can be manually wound before setting the time.
Mechanical accuracy may vary depending on power reserve, wearing habits, temperature and resting position.

Wearing and Care Advice
Clean the case and bracelet regularly with a soft microfiber cloth to remove fingerprints, sweat and dust.
