Introduction
The wristwatch, an epitome of precision, elegance, and status, has evolved throughout the decades. Yet, while many marvel at the watch’s face and design, few appreciate the wristwatch case back. It’s more than just the rear part of a watch; it is the window into the very soul of the timepiece.
Wristwatch Case Back: An Overview
While the front of a wristwatch grabs attention with its intricate hands and markers, the case back holds mysteries of its own. Often overlooked, it is instrumental in the watch’s protection, functionality, and sometimes, aesthetic.
Materials and Manufacturing
Most wristwatch case backs are made from stainless steel, titanium, or ceramic. These materials are chosen for their strength, durability, and resistance to corrosion. The process of making a case back involves detailed machining, polishing, and sometimes engraving.
Types of Case Backs
There are several types of wristwatch case backs:
Snap-On (Snap Back): This is a case back that simply snaps into place. It’s generally removed using a knife edge or a specialized case back remover tool. The snap-on back sits in a shallow groove on the case, holding it in place.
Screw Down (Screw-In): As the name suggests, this type of case back is screwed onto the watch case using a thread. They offer better water resistance than snap backs. To open them, special wrenches with adjustable notches are used to fit into the grooves on the back of the watch.
- Screwed-Down (with Screws): These case backs are fastened to the watch case with typically four to eight small screws. They’re usually found on high-end watches or watches made for specialized purposes, such as diving.
- Monocoque (One-Piece): In this design, the watch case is made from a single piece of material. The movement and other components are inserted from the front of the watch, and the dial and crystal are the last parts to be placed. This offers good protection against water and dust, but servicing can be more challenging because everything has to be removed from the front.
- Display or Exhibition Back: Typically made of transparent sapphire crystal, this type of case back allows the wearer to see the inner workings of the watch, showcasing the movement and any decorative elements. It can be either a snap-on or a screw-down.
The Seal: Ensuring Water Resistance
The wristwatch case back isn’t just about aesthetics. It ensures the watch remains water-resistant. A special gasket, usually made from rubber or silicone, ensures no water or dust penetrates the watch.
How to open these case back
Snap-On (Snap Back):
- Tools Needed: Case knife or case back opener.
- Method: Insert the blade of the case knife into the small gap (usually a small notch) between the case back and the watch body. Gently twist or pry the knife to pop off the back.
Screw Down (Screw-In):
- Tools Needed: Case wrench or case back opener with adjustable notches.
- Method: Adjust the notches on the case wrench to fit into the grooves on the case back. Once it’s securely in place, turn counter-clockwise to unscrew and open.
Screwed-Down (with Screws):
- Tools Needed: Small precision screwdriver.
- Method: Using the screwdriver, unscrew each of the screws. Keep these tiny screws safe, as they’re easy to lose.
Display or Exhibition Back:
- Tools Needed: Depends on whether it’s a snap-on or screw-down type. Use methods as described above.
- Method: Handle with care, especially since the crystal can easily scratch or crack
Some additional notes:
- Always ensure you’re using tools that are clean and in good condition to avoid scratching or damaging the watch.
- If you’re unsure about opening a particular watch case back or if it seems to be unusually tight or stuck, it might be best to consult with a professional watchmaker or technician.
- After opening, especially in the case of water-resistant watches, ensure all seals or gaskets are in good condition and properly placed when re-sealing the watch. If you’re unsure about the water resistance, it’s recommended to have the watch tested or resealed by professionals.
- Always keep a soft cloth or cushion beneath the watch to prevent scratches or damage during the process.
