As a surgeon with two decades in the operating room, I have seen many things. But one question that comes up often from patients is about the watch on my wrist. They notice it, and they wonder. Let me explain the practical reasons behind this choice, and what it means for you.

First, understand that a surgeon’s watch is not a status symbol. It is a TOOL. We need reliability, legibility, and hygiene. A watch worn in surgery must be easy to clean, resistant to fluids, and provide quick, accurate time reading. Luxury brands like Rolex, Omega, and Patek Philippe are popular because they meet these demands. They are built to last, with sapphire crystals that resist scratches and surgical-grade steel that withstands repeated sterilization.

Here are three key features surgeons look for in a watch:

1. EASY LEGIBILITY. We cannot afford to squint. A clear dial with bold, contrasting hands and markers is essential. White or light dials with dark hands are preferred. Avoid busy chronographs or small numerals. The time must be read in a split second.

2. WATER AND CHEMICAL RESISTANCE. Operating rooms are wet environments. Blood, saline, and disinfectants are constant. A watch must be water-resistant to at least 100 meters. Rubber or metal bracelets are better than leather, which soaks up fluids and bacteria. Many surgeons choose the Rolex Submariner or Omega Seamaster for this reason.

3. ACCURACY AND DURABILITY. A mechanical movement that loses or gains seconds over a day is unacceptable. Quartz watches are often more accurate, but many surgeons prefer the craftsmanship of automatic movements. Brands like Grand Seiko and Patek Philippe are known for exceptional precision. The watch must also withstand bumps against equipment and patient beds.

Now, for practical advice you can use. If you are considering a luxury watch for your own use, whether for work or daily life, apply the same logic. Do not buy a watch that is hard to read. Do not buy one with a leather strap if you work with your hands or wash them frequently. Do not buy a watch that is too heavy or bulky, as it can catch on clothing or get in the way.

For patients, here is a simple step: When you see your surgeon wearing a particular watch, it often means they value function over fashion. It is a sign of someone who thinks about details. If you are shopping for a watch yourself, ask the jeweler about water resistance, crystal type, and movement accuracy. Test the legibility in low light. A good watch should be comfortable, reliable, and easy to clean.

What to remember: The watch on a surgeon’s wrist is a reflection of their work environment, not their ego. It is chosen for performance, not prestige. The same principles apply to any tool you use daily. Whether it is a watch, a phone, or a kitchen knife, choose for function first.

In my experience, the best watch is the one you never have to think about. It just works. So, when you see a surgeon with a Rolex, do not assume it is about money. It is about having a reliable partner for the long hours ahead. That is a lesson we can all take to heart.
