Stylish and lightweight - makes titanium bracelet extra special. This high quality material is resistant to corrosion and is very gentle to the skin (no nickel), so it could be used by people with nickel allergies.
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.
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: 200 meter (20 bar)
This watch can be worn while swimming/snorkeling (near the surface). 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).
Titanium case This watch is produced in titanium, which is characterized by being lighter than steel and free from nickel.
Does this watch fit your wrist? Wristwatches has gradually become larger in size, and a typical men's watch is usually between 40 and 45 mm wide. If you have a wrist that is noticeable larger/smaller, we recommend that you focus on the sizes in/outside the outer edges of the typical sizes. You are always welcome to contact our support, so we can share our experience with you.

How is the size of the watch measured?
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
