Numbers on the back of the watch

The numbers on the back of a watch help you understand your watch’s size and how it will fit your wrist. There are three main measurements that you’ll see on the back of a watch: the diameter (in millimeters), the lug-to-lug distance (the distance from one side of the watch’s strap to the other), and the thickness (in millimeters).

Knowing the thickness is helpful because if you’re buying a watch for a friend or loved one, you may want to find a watch that will fit them well.

Reference and Serial Numbers

The reference number on the back of a watch is what it was initially sold for. It is usually stamped into the back of the watch, and sometimes it is a number that the owner has added to the watch.

A serial number is what you see when you register your watch with the manufacturer. This is a number that the manufacturer uses to track the watch as it goes through the production process. The serial number is usually located on the back of the watch.

Every watch is assigned a reference number and a serial number. A reference number is a number assigned to a specific watch, which is usually the number of the watch’s factory.

A wind stem is a device that is pulled to wind the mainspring of a watch. Winding branches were first used in the 1880s and improved over the earlier essential type of watch winder.

A vital watch winder requires the user to remove a key from their pocket to wind the watch. Wind stems replaced the key because they were more convenient. In contrast, a winding stem can be pulled with one hand while the other hand is used to perform other tasks.

Different watch styles and how they display watch numbers

Like the round watch with Arabic numerals on the face, some watch styles show the hour and minute hands simultaneously. This is perfect for telling the time with accuracy.

The following style watch is a rectangle watch with Roman numerals on the face and the hour hand is always on the right side of the face. This is great for telling the time more traditionally.

The last watch style is the digital watch with a small display showing the time in numbers. This is ideal for telling the time without knowing how to read the time on a traditional watch. Round watches with Arabic numerals on the face are great for telling the time with accuracy.
