Why Poor-Quality Watch Services Use Strong Mainsprings

Low-quality watch services often cut corners to save time and money, and one common issue is the use of overly strong mainsprings. Instead of sourcing the correct, model-specific mainspring, some technicians may use a stronger one as a quick fix to compensate for other issues within the movement.

A strong mainspring provides more power to the movement, which might temporarily mask problems such as worn gears, dirty components, or improper lubrication. By forcing the movement to run harder, these underlying issues can be hidden—but only for a short time. Over time, the extra stress from the strong mainspring causes accelerated wear to the gears, pivots, and other delicate parts of the movement.

Another reason is the availability of generic parts. Poor-quality service providers may not have access to the proper manufacturer-approved components and instead opt for generic mainsprings that aren’t precisely matched to your watch. This lack of precision often results in a stronger-than-required mainspring being installed, compromising the watch’s performance and longevity.

In short, using a stronger mainspring may seem like an easy solution, but it reflects poor workmanship and can lead to significant damage over time. Choosing a professional service provider with access to the correct parts and expertise ensures your watch receives the care it deserves.
