The diameter of your timepiece, expressed in millimeters, is a silent announcer of style on your wrist. It whispers tales of the watch’s internal mechanics and the design era it hails from. To demystify these numbers, we’ve crafted a comprehensive guide to finding your perfect watch size.

• Under 36mm: The Vintage Charm

Modern catalogs may not showcase many options under 36mm, but vintage collections tell a different story. These smaller sizes were once the standard, offering a vast array of choices for the discerning collector. While wrist sizes haven’t changed, preferences have, making the classic sub-36mm watch a unique statement piece. For those seeking subtlety, a vintage gold watch from the 1950s, paired with a patent leather strap, can add just the right amount of sophistication peeking out from a shirt cuff.

• 36-38mm: The Return of Elegance

Recent trends have seen a shift away from larger, more ostentatious watches back to the refined 36-38mm range. This resurgence balances the catalog with options that cater to a broader audience, including women who desire elegance without the frills. The revival of mid-century designs in their original sizes brings a sense of authenticity and, simply put, sensibility to the selection.

• 38-41mm: The Contemporary Classic

For a modern look that complements almost any attire, from formal to casual, the 38-41mm range is ideal. If your wrist circumference is within the average male range of 16–19cm, this size offers a noticeable yet tasteful presence. It’s fascinating to consider that what was once deemed ‘oversize’ is now the epitome of style and versatility. 

• 42-44mm: Bold and Distinguished

Stepping into the 42-44mm category, you enter the realm of the "oversize" - a concept pioneered by iconic brands like IWC Schaffhausen and Officine Panerai. These sizes pay homage to historical precision and purpose, from the Portugieser’s pocket-watch origins to the Luminor’s military-grade durability. For those with larger wrists, this range provides ample choice without compromising on style or comfort.

• 45mm and up: The Statement Makers

Watches exceeding 45mm are for the bold, the trendsetters who aren’t afraid to make a statement. These sizes can be traced back to historical models like IWC’s Big Pilot, originally designed for aerial navigation. Today, they represent a choice for those who dare to stand out, much like the striking design of Bell & Ross’ BR 01.

• The Often-Overlooked Z-Axis

In the digital age, the thickness of a watch, or its z-axis, is frequently overshadowed by its face-on appeal. Yet, this dimension significantly influences the watch’s profile and how it interacts with your attire. From the JLC Master Ultra-Thin Squelette to the robust divers’ watches, the thickness must harmonize with the watch’s overall design and function.

• Measuring Your Wrist for the Perfect Fit:

1. Rest your hand, palm up, on a flat surface.
2. Spread your fingers slightly to ensure an accurate measurement at its fullest point.
3. Encircle your wrist with a measuring tape just above the wrist bone, making a complete loop.
4. Note the measurement where the tape meets its starting point, using inches or centimeters for precision.
