Invicta Subaqua Noma IV Chronograph 6582
Swiss RONDA 5040.D clockwork
This watch uses a Swiss RONDA 5040.D precision clockwork, and you are probably already familiar with that Swiss Made clockworks are the best and most famous in the world.
Sapphire glass
Sapphire is up to 7 times harder than steel, and surpassed only by diamonds on the Mohs scale. This makes sapphire glass a great protection for your watch.
Chronograph
Used for measuring time intervals (also called: Stopwatch). Often constructed as smaller dials in the center of the major dial.
Tachymeter
Used for calculating. For example, the time it takes a car to drive 1 km is converted to speed/time.
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.
Screw locked backside
Protecting the delicate inside and also provides an easy access when you need to replace the battery.
Screw crown
Prevents penetration of water. To set the watch, the crown must first be screwed up.

This watch can be worn while 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).

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
If you buy this watch together with: and ; tools to easily adjust/replace your bracelet/strap, we will give you a big discount.
