The Ultimate Luxury Watch Sizing Guide: How To Measure Watch Size

Read our Best Luxury Waterproof Watches size guide to understand how to measure a watch in three simple stages, including wrist size, case size, as well as bracelets and straps, and how to determine the correct watch size.

Take a Measure of Your Wrist

It is critical to first determine your personal wrist size before selecting the appropriate watch size. It is possible that your wrist size will differ somewhat based on whether or not you wear your watch on the left or right wrist. The circumference of your wrist may be determined by using a measuring tape to measure the circumference of your wrist. 

The size of your wrist may influence your decision on whether to choose a watch with a small or big case. The traditional rule is that smaller wrists choose smaller cases and bigger wrists choose larger cases, albeit this may be fully dependent on personal desire and taste.

How to find out what size your wrist is:

Placing your hand palm up on a level surface is a good idea.

Spread your fingers slightly (doing so will guarantee that you receive the true measurement of your wrist when it is at its biggest) and measure your wrist.

Measure your wrist just above the joint using a measuring tape. Repeat the process until the tape has gone all the way around your wrist and hits the beginning of the tape. You may want to enlist the assistance of a buddy for this.

Look at the length of the measuring tape, which should be in inches or centimetres.

What methods are used to measure and size watch cases?

Case Sizing Chart to the Rescue!

When it comes to watches, the case size is the most distinguishing aspect, thus it is essential that it be the proper size for the user. Calculating case size requires taking an accurate measurement in millimetres (mm) from the watch’s outside corners at its widest point, excluding the crown. A calliper measurement instrument is often used to determine the exact diameter of a timepiece.

Case Forms are a kind of case that is shaped like a box.

When it comes to the form of a watch case, there are several alternatives to pick from, including round, oval, square, rectangular, cushion, and tonneau shapes. All of these forms are distinct from one another, however they all have the same or very similar case sizes. Other than the form of the case, elements such as the geometry or design of the case, such as the thickness of the bezel or the size of the dial, may actually make the watch seem smaller or larger on the wrist when it is in reality not there. Depending on your own taste, you may like a more typical circular case, or for something a bit more beautiful.

Thickness of the case

It is possible to measure the thickness of a watch by measuring from the centre of the crystal on top to the centre of the case back on the bottom. The usual method of measuring this is likewise with the use of a calliper instrument. A thicker casing is often seen in watches with greater case diameters. The result is that an oversized watch will be bulkier and heavier, whilst a smaller watch will be sleeker and lighter in comparison to its larger counterpart. 

The thickness of a watch is typically proportional to how many different collections it has. Typical watch thicknesses range from around 7 to 9 millimetres for watches with diameters ranging from 38 to 42 millimetres, and 9 millimetres for watches with diameters more than 44 millimetres. While the choice of case thickness is entirely up to the wearer’s own preference and style, most individuals who have a tiny wrist prefer a thinner option. Large and hefty timepieces, on the other hand, are becoming more and more popular.

Bandanas, bracelets, and other similar accessories

When purchasing a watch, it is also important to consider the size of the band or the strap. In most cases, the breadth of the bracelet is about half the diameter of the case of a well-proportioned watch. A 40mm watch should have a width of roughly 20mm if worn with a 20mm band. Furthermore, metal bands have a chunkier appearance than leather straps, however this might vary depending on the watch manufacturer. 

Other watch companies may also use rubber straps, as is the case with Rolex which offers a wide variety of band designs. If you want to learn more, check out our luxurious watch strap guide.
