Seiko 7C46 clockwork
This watch is powered by a high quality quartz clockwork; Seiko 7C46 - which is used in Seiko's most durable diver's watched. It was produced to be able to withstand extreme conditions, and has a built-in EOL (End Of Life battery-function), which causes the second's hand to only move every other second, instead of each second - when the battery is running out of energy, and need to be replaced. It also makes remaining battery power last longer. "Unfortunately", the clockwork is of such high quality so that the life expectancy is about 5 years = it will take a long time before you'll be able to appreciate this function.
Resistant to magnetic fields
This case is designed to protect against magnetic fields.
Rotating bezel
This watch is equipped with a rotating bezel, which can be used to mark the beginning/ end of a time interval.
Screw crown
Prevents penetration of water. To set the watch, the crown must first be screwed up.
Luminous layer
A luminous layer provides a long-term lightning effect in the dark. It requires only a short-term exposure to light. Usually the pointers, and sometimes the hour markers are coated with this.
Display of day and date
Current day and date is displayed on the dial/screen.
Safety mechanism
This watch has an extra safety mechanism, which prevents the lock from getting opened by accident.
Stainless steel bracelet
Tough, durable and elegant; a bracelet made of stainless steel gives the watch a classic quality look.
Mineral crystal
This, very durable, mineral crystal has improved protection.
Quartz Watch
A battery-powered quartz watch is controlled by fluctuations in a crystal of the mineral quartz. These oscillations change very little over time, which is why quartz is often used - because it retains its accuracy.
Water protection: 300 meter (30 bar)
This watch can be worn while swimming/snorkeling and even shallow diving. The value refers to the pressure in water, at that depth, while motionless... and should not be seen as the depth for wearing the watch.
Condensation - important!
Rapid changes in temperature can cause condensation inside the watch. If you notice moisture beneath the glass, you should immediately go to a watchmaker, who can open and dry the watch. Even if the signs of moisture disappears, by themselves... the moisture will not - and will eventually damage your watch - so, visit a professional and remove it permanently. Even waterproof watches are not protected against condensation, so keep that in mind if you plan to go from very hot to very cold temperatures - like from a hot sauna directly to the snow. If condensation occurs, it very rarely (if ever) depends on manufacturing, so if your watch is damaged by moisture, warranty will probably not cover it (it could be manufacturing issues, but... most likely it will be because of the rapid change of temperature = natural causes).
Case made of stainless steel.

How is the size of the watch measured?
The diameter
The common term is diameter, but since not all watches have circular watch cases, the diameter is actually the width measured from left to right. Note that some manufacturers include the crown (to set the clock) and the buttons when measuring the width, but we try to standardize all the watches by not including the crown as part of the measured width.
The thickness - or height of the watch in profile - is indicated by measuring the watch from top to bottom as illustrated below. By comparison, a 1-euro coin is 2.33 millimeters thick.
One usually defines the watches with these numbers:
Slim: 4-6 millimeter
Normal: 6-12 millimeter
Big: 12-14 millimeter
Oversize: 14-18 millimeter
