How Does a Waterproof Watch Work?

• Waterproof watches are most commonly sought out by those who engage in water activities, such as diving or snorkeling. Waterproof watches incorporate the use of O-ring seals at two major points of potentially water entry. The stem, the small knobbed pin that is pulled from the side of the watch for time and date setting, is typically sealed with an O-ring that is reinforced by a screw down feature on the stem. This allows for a secure seal against potential water entry. The case back is perhaps the largest point of water and moisture entry and once again utilizes O-rings that are screwed down tightly against the watch itself.
• The Crystal
• The crystal of a waterproof watch will typically receive a waterproof sealant during the manufacture of the watch. Located beneath a rotating measurement bezel can be other seals such as O-rings, incorporated to aid is sealing out water and moisture.
• The Band
• Waterproof watches will feature bands that also have water and moisture resistant features. Made of either rubber, plastic or waterproofed leathers, these bands provide a functional as well as attractive complement to waterproof watches. From a functional standpoint, many dive bands will feature oxygen consumption references and even compasses.

How Does a Digital Watch Work?

• Basics
• A watch is essentially a clock, and all clocks work basically the same way. There is a power source, which in a watch is a small battery. There is an accurate time base and a way to gear down the timebase. This is the heartbeat of the watch and what keeps the watch at the correct time, hours, minutes and seconds. Each watch also has a unique design and way to display the time.
• Power Components
• A digital watch works the same way as a mechanical watch, but instead of using mechanical workings, it uses electricity to function. A digital watch uses an electronic power supply, usually a small round, flat, watch battery. While a mechanical watch ticks as it keeps time, a digital watch uses an electronic time base. This is also known as the accurate rate, and the gearing mechanics are referred to as the counter. The face of the watch is lit up by either an LED or LCD.
• Producing the Numbers
• The counters need a drive to display the numbers. The counter uses binary numbers. The counter creates a zero, one, two, three, four, five, six, seven, eight and nine number sequence. It then uses this sequence to display the time by blocking out sections of the numbers, thus displaying the correct numbers in the most accurate order which reads the current time.
