QF Factory builds Rolex GMT-Master II and Yacht-Master references, and its reputation rests on one thing: getting two tone ceramic bezels right.

A workshop known for one component
QF, sometimes written Quality Factory, is unusual in being associated with a part rather than a model. What it is known for is the bezel, and specifically the two colour ceramic bezels on the GMT-Master II.
That sounds like a small thing to build a reputation on until you understand why it is hard.
Why a two tone ceramic bezel is difficult
Ceramic is fired, and colour goes in before firing. A single colour bezel is straightforward. A bezel that is blue on one half and black on the other, with a clean vertical boundary at twelve and six, is not, because the two ceramics have to be joined and fired without the boundary bleeding or the piece cracking at the join.
Rolex spent years solving this and the result is the Batman, the Pepsi and the Sprite. Get the boundary wrong on a replica and the watch fails at arm’s length, because the bezel is the largest and most colourful thing on it.
The second problem is the colour itself. Rolex red on a Pepsi is a specific red, and ceramic reds are notoriously hard to fire consistently. Most replica Pepsi bezels come out either too orange or too pink, and the error is obvious next to a real one.
What QF builds
- GMT-Master II Pepsi. The red and blue, which is the hardest of the three.
- GMT-Master II Batman. Blue and black, the cleanest boundary of the set.
- GMT-Master II Sprite. The green and black left hand crown reference.
- Yacht-Master. Raised numeral bezel work, which is a different but related problem.
What QF is not
A movement workshop. QF’s reputation is built on the exterior, and on the calibre side it is competent rather than leading. For the closest movement work on a GMT you are looking at the workshops running proper 3285 clones, such as EWE.
That is a genuine trade off rather than a criticism. On a GMT the bezel is what everyone sees and the movement is what nobody sees, so which one you prioritise is a real decision rather than an obvious one.
What does one cost?
Our GMT-Master references run $1,200 to $1,350 and the Yacht-Master sits at $1,200. Every figure is printed on the product page.
Checks before buying a two tone bezel
- Ask for a straight on bezel photograph in daylight. Colour accuracy cannot be judged under a warm indoor light, which is how most listing photographs are shot.
- Look at the boundary at twelve and six. It should be a clean vertical line with no bleed and no step.
- Check the numerals. The engraved and filled numerals should be even in depth all the way round the bezel.
Frequently asked questions
What is QF Factory known for?
Two tone ceramic bezels on the Rolex GMT-Master II, covering the Pepsi, Batman and Sprite references, plus Yacht-Master bezel work.
Is QF the same as Quality Factory?
Yes, the names are used for the same workshop.
Why is the Pepsi bezel the hardest?
Because ceramic red is difficult to fire consistently and it has to meet blue at a clean boundary. Most replica Pepsi bezels come out too orange or too pink.
Is QF good on movements?
Competent rather than leading. Its reputation is built on the exterior. For the closest GMT movement work, look at workshops running proper 3285 clones.
Where can I see the range?
Our GMT-Master collection and the Yacht-Master range carry the references.
