Don't Drop Your Watch Without Reading This First

Annena Sorenson

We've all heard the term "shock resistant" in the watchmaking world. However, what does this term really mean and is your timepiece resistant enough to absorb shocks caused by falling, dropping, exerting too much acceleration at once, and more?

It is a viable question in today's fast-paced world where active lifestyles put us on the edge of powerful sports and lifestyle engagements all the time. As such, today's top watchmakers are going to new heights to make their watches sturdier so they can withstand the rigors of daily life.

Essentially, a truly shock-resistant watch is one whose movement is not damaged when dropped or subjected to constant impactful motions (i.e., worn on the wrist during a tennis match). Generally, watch brands achieve this via different types of suspension systems for the balance wheel. Such systems include pivots that can hold a balance wheel in place, while offering enough "give" to go with the situation or even more complex multi-level suspension processes.

The most commonly used system is the Incablock — invented in the early 1930s and perfected time and again. Incablock is a trade name for a spring-loaded mounting system for the jewel bearings that support the mechanical watch’s balance wheel. Some brands today combine the Incablock system with synthetic jewels, silicon hairsprings, non-ferrous escape wheels, outer housing containers, ceramic ball bearings and other high-tech materials and trains that make the watch movement ever more resistant to blunt force trauma.

The International Organization of Standardization (ISO) has also issued certain standards of shock resistance. In the watch world, to be called shock resistant, a watch must meet certain tests and controls and adhere to the standards of shock resistance issued by the ISO, including keeping accuracy while undergoing shock of +/- 60 seconds/day. Additionally, most watch brands using shock resistant movements also use top-quality case and crystal materials to avoid breakage.

Is your watch shock resistant? If you have purchased a certified chronometer, yes. Other watches that are shock resistant mostly include dive watches, pilot watches and certain high-tech sport watches. Stop in any time to discuss shock resistance with us and to find the watch that is right for your active lifestyle.
