A watch that loses time, stops, shows signs of moisture, has a winding crown that is difficult to wind, or simply seems less regular does not always require the same type of intervention. Before talking about servicing, repair or replacement parts, a watch diagnosis helps identify the origin of the issue and guide the watch towards the most appropriate solution.
In Aix-en-Provence, the Mostra Store watchmaking workshop welcomes owners of mechanical, automatic, quartz, vintage and collector watches for an initial check, functional assessment and, when necessary, a quote before any intervention.
Why have a watch diagnosed before any intervention?
A watch diagnosis helps understand what is really happening before any work is carried out. A watch that stops may require a simple restart, a full service, a targeted repair, a battery replacement or a more in-depth check.
This step avoids rushing into the wrong solution. It helps distinguish preventive maintenance from a fault, a usage-related issue from a mechanical problem, or a simple intervention from a more complex repair.
At Mostra Store, diagnosis therefore acts as the starting point: it allows the team to identify symptoms, assess the general condition of the watch and guide you towards the most coherent solution.
Which signs indicate that a watch should be checked?
Certain signs should prompt you to have a watch checked without waiting. They do not always mean that a major repair is required, but they deserve a professional eye.
- A watch that stops for no apparent reason
- A significant loss of accuracy
- An automatic watch that no longer holds its power reserve
- A crown that is difficult to operate
- Fog or moisture under the crystal
- A recent shock or fall
- A seconds hand behaving unusually on a quartz watch
- An abnormal noise inside the case
- A strap or attachment that seems weakened
In these situations, diagnosis helps prevent a small issue from becoming more costly or more delicate to address.
Diagnosis, servicing or repair: what is the difference?
A diagnosis is not a service, and it is not yet a repair. It is an assessment stage that helps understand the condition of the watch and identify the nature of any possible intervention.
Diagnosis
Diagnosis is used to observe symptoms, check general functioning and determine the likely origin of the issue. It then allows the workshop to provide a clear recommendation.
Servicing
Servicing refers to the complete maintenance of the movement: disassembly, cleaning, lubrication, adjustment and checks. It mainly concerns watches whose movement needs maintenance to preserve precision and longevity.
Repair
Repair is required when a malfunction or fault has been identified: worn or broken part, crown issue, blocked movement, moisture ingress or component replacement.
After diagnosis, the workshop may therefore guide you towards watch servicing in Aix-en-Provence, watch repair in Aix-en-Provence or a simpler intervention depending on the actual condition of the piece.
How does watch diagnosis work at Mostra?
Diagnosis begins with the observation of the watch and the information you can provide: symptoms noticed, date of the last service, recent shock, exposure to water, sudden stop or loss of accuracy.
Depending on the situation, the workshop may carry out several checks:
- visual inspection of the case, crystal, crown and strap;
- observation of general functioning;
- check of the movement’s accuracy or behaviour;
- assessment of the apparent condition of the watch;
- identification of a possible need for servicing, repair or parts replacement;
- orientation towards a quote if an intervention is required.
The objective is not to replace a full appraisal or an in-depth service, but to establish a reliable first reading in order to decide on the next step.
A quote before any watchmaking intervention
When diagnosis reveals the need for intervention, the Mostra Store workshop informs you of the possible solutions, the type of operation being considered and the estimated timeframe depending on the complexity of the watch.
No significant intervention is carried out without your prior approval. This step helps maintain a clear relationship: you understand what is recommended, why it is recommended, and under what conditions the watch can be handled.
Depending on the model, its condition and the possible availability of parts, the quote may require a more detailed examination before confirmation.
Diagnosis of mechanical, automatic, quartz and vintage watches
The Mostra Store watchmaking workshop can diagnose different types of watches: manual mechanical watches, automatic watches, quartz watches, chronographs, dive watches, vintage watches and collector pieces.
Each type of watch presents its own symptoms. An automatic watch may become less regular, a quartz watch may show signs of a weak battery, a vintage piece may require a more cautious approach, while a watch exposed to water should be examined quickly.
For antique or collector watches, diagnosis also helps determine whether an intervention should follow a preservation-oriented approach, in order to maintain the coherence of the piece as much as possible. You can explore this topic further on our page dedicated to vintage and antique watches at the workshop.

No. Diagnosis helps identify the likely origin of the issue and determine the necessary intervention. A repair, service or more in-depth examination may then be recommended.
Diagnosis is an assessment stage. Servicing is a complete technical intervention that involves disassembling, cleaning, lubricating, adjusting and checking the movement.
Yes, when an intervention is required, a quote is provided before any repair or major operation. No intervention is carried out without prior approval.
Yes. Vintage and older watches can be checked with particular attention paid to their condition, coherence and preservation.
It is generally possible to bring a watch directly to the boutique during opening hours. For a specific request or a particularly complex watch, it may be useful to contact the team in advance.
