Tudor Pepsi GMT Replica Review – ZF Factory Edition

[...]

The Tudor Black Bay GMT (Ref. M79830RB-0010) has been a popular choice among watch enthusiasts for its striking "Pepsi" bezel and robust GMT functionality. ZF Factory, a well-known name in the replica watch industry, has attempted to recreate this iconic timepiece with impressive accuracy. In this review, we’ll examine the key aspects of the ZF Factory Tudor Black Bay GMT replica watch, comparing it to the genuine model and assessing its strengths and weaknesses.

Case & Bezel: A Close Match to the Original​

The ZF Factory replica features a 41mm stainless steel case with a combination of brushed and polished surfaces, closely mimicking the original Tudor Black Bay GMT. The case thickness is 14.7mm, just 0.1mm thicker than the genuine model, making it nearly indistinguishable on the wrist.
The most eye-catching feature is the bidirectional rotating "Pepsi" bezel, made from anodized aluminum (like the authentic version) rather than ceramic. The red and blue colors are subdued—red leans towards burgundy, while blue has a darker, almost black hue under certain lighting conditions, matching the original’s aesthetic. The bezel action is smooth, with 48 clicks for precise adjustment, just like the genuine model.

Dial & Hands: High-Quality Replication​

The matte black dial features the signature Tudor "snowflake" hands, which ZF Factory has replicated with great precision. The GMT hand (red "snowflake") functions correctly, allowing for tracking of a second time zone, while the 24-hour bezel enables a third time zone—just like the original.
The hour markers and hands are filled with Super-LumiNova, providing strong lume that closely resembles the genuine watch. However, some users note that the date wheel font is slightly thicker than the original, which could be a minor tell for those familiar with the authentic model.

Movement: Reliable but Not 1:1​

The ZF Factory replica uses a modified Seagull 2836 automatic movement to simulate the functions of Tudor’s in-house MT5652 GMT movement. While it keeps decent time (±15 sec/day) and offers the same GMT functionality, it lacks the refined finishing and METAS certification of the genuine movement.
Since the watch has a solid caseback, the movement’s appearance isn’t visible, making this a non-issue for most buyers. However, purists may prefer a more accurate clone movement.

Bracelet & Clasp: Solid Construction​

ZF Factory replicates Tudor’s signature "riveted" stainless steel bracelet with a trapezoidal link design, matching the original’s look and feel. The clasp is sturdy, though it lacks the genuine Tudor’s T-fit micro-adjustment system, which is a notable omission.

Final Verdict: One of the Best Tudor GMT Replicas​

ZF Factory’s Tudor Black Bay GMT M79830RB-0010 replica is one of the most accurate reproductions available. The case, dial, and bezel are extremely close to the original, with only minor flaws (such as the date wheel font and movement differences). For those who want the look of a Tudor GMT without the high price, this replica watch is a compelling option.

Discussion Points​

1. How important is movement accuracy in a replica watch? Would you prefer a cheaper but less accurate movement, or a more expensive clone movement that mimics the genuine watch?
2. Does the lack of a ceramic bezel affect your decision? The genuine Tudor uses aluminum—do you think a ceramic upgrade would make the replica better?
3. Would you wear a high-quality replica watch in professional settings? Or do you think replicas should only be for personal enjoyment?
4. What other Tudor replicas would you like to see improved? (e.g., Black Bay 58, Pelagos)
