Product Description

Official reseller
We are an official reseller of all brand's watches that we sell. That equals to: genuine watches with valid warranty and access to official service.

Dual illumination
Both the digital and the analog part of the dial/screen becomes illuminated when you activate illumination.

Shock resistant
A so called shock resistant construction protects the watch against shocks and vibrations.

Display of day and date
Current day and date is displayed on the dial/screen.

A luminous coating requires xposure to light, to provide a light effect in the dark.

World clock
The largest cities in the world are pre-programmed in this watch, so you can select current city/town (closest to you, in the same time zone), and the watch automatically shows the correct time.

Stopwatch function - 1/100 sek. - 24 hours.
Preliminary time, split time and final time are measured down to 1/100 of a second's accuracy. The measuring capacity is up to 24 hours.

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. The time can be set in second intervals up to 100 hours in advance. Therefore this function is especially useful in for daily intake of medicine/treatment or for interval workout.

5 daily alarms
The alarms are using an acoustic signal that could remind you of repeating events at a set time. You can also set a time signal that indicates each full hour. This model has five independent alarms for flexible reminders of important appointments/events.

Keyboard sounds on/off
The keyboard sound can be deactivated. This does not affect any other functions of the watch, like alarms, timers, reminders.

12/24-hour timing
The time can be specified either in a 12 hour (AM/PM) or in a 24 hour format.

The watch automatically adjust for different months different lengths, and for leap years.

Long batterylife
Because of this watch's low energy usage, the battery will last at least 2-3 years.

Used for measuring time intervals (also called: Stopwatch). Often constructed as smaller dials in the center of the major dial.

Resin strap
Natural resin is an ideal material for straps, because the material is not only very durable but also very flexible.

Mineral crystal
This, very durable, mineral crystal has improved protection.

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).

Size This watch has a width of 46 mm (the dial, measured from left to right, with the crown excluded). Even if some watches are not perfectly circle shaped, we still use the term: diameter - and we only measure the case, completely ignoring the crown (even though some includes it, in their measurements).

Resin case

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.

    Size Guide

    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.

    size info
    Case Thickness
    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

    Tools and maintainance

    If you buy this watch together with: Watch sizing tool for metal bands ($24 value) and To change strap/spring bars - ($15 value); tools to easily adjust/replace your bracelet/strap, we will give you a big discount.

    We also recommend Cape Cod Polishing Cloth + Buffing Cloth, for removing scratches on metal - or if you just want to make it look new again. If you have scratches on glass, then this is the item for you: Beco Polywatch Lens Polishing Cream 211147.
