Technical reviewer of the Korean source: 박성희 · 대표
Translated from the technically reviewed Korean article.
Can I ask about a Franck Muller repair without knowing the exact model number?
Share a front photo, the lettering visible on the dial, and the changes you noticed and when you first noticed them. This article uses internal disassembly, assembly and hand-fitting scenes from one source video to help you prepare an inquiry.
At a glance
This case at a glance
The video shows work on a Franck Muller with a tonneau-shaped outline, black dial and red numerals.
Internal disassembly starts at 9 seconds; assembly begins at 33 seconds, followed by hand fitting.
For an inquiry, share a front photo, visible markings, when you first noticed the issue and when it recurs.
Starting with the watch's appearance
A black dial, red numerals and a tonneau-shaped outline introduce the Franck Muller in this video. In the exterior scene, the exterior and dial appear together, and the dial bears the wording CONQUISTADOR. These visible details and the lettering you can read are useful starting points when describing a watch.
A repair inquiry can begin by showing the watch you own. A front photo conveys the numeral color, dial lettering and case outline together. Even when you know the model name, including a photo gives the conversation a clear visual reference.

Internal gears and a separated plate
The internal disassembly sequence begins at 9 seconds. The photos show internal gears, a separated plate and the gears below it. The view moves from the dial to the components inside, showing a different aspect of the work from an exterior photograph.
In the gear scene, look at the arrangement of the components; in the plate scene, follow the appearance of the separated plate itself. You do not need to memorize every component name to connect the exterior with the interior as the sequence unfolds. These visible scenes form the focus of this process introduction.


How to describe the model and symptoms
For an inquiry, send a front photo, any model wording you can read, when you first noticed the issue and the circumstances in which it recurs. If you are unsure of the model number, share the lettering on the dial as it appears. Describing visible features such as a black dial and red numerals alongside a photo is also useful.
Describe what you experienced rather than guessing a cause. If your watch has stopped, for example, note when you first noticed it and whether it remains stopped or the issue occurs intermittently. This is an example of preparing an inquiry. Contact us through the inquiry page or at 02-777-5031 with the watch's appearance and the issue you have experienced.
From internal assembly to fitting the hands
The internal assembly scene is followed by hands being fitted above the dial. The sequence returns from the internal gears and separated plate to the dial, connecting the face used to read the time with the work inside.
You can view one work video in two sections: internal disassembly and assembly. The disassembly link begins at 9 seconds and the assembly link at 33 seconds. Continue to the later exterior view to see the black dial and red numerals again.
