A light diode (light-emitting diode/LED) is used for lighting up the front of the watch.

Timer – 1/1 min – 24 timer (with auto repeat)
Useful general information: Countdown hour can provide reminders for special or repeating events. The hours are also counted back automatically from the defined time.

Stainless steel bracelet
Tough, durable and elegant; a bracelet made of stainless steel gives the watch a classic quality look.
Acrylic glass
This dial is protected by acrylic glass, treated for extra durability.
Water protection: 50 meter (5 bar)
This watch can resist water, but should not be worn while swimming. 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).
Resin case
Sizes
Does this watch fit your wrist? Wristwatches has gradually become larger in size, and a typical women's watch is usually between 32 and 38 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 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.
