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.

Full automatic Illuminator
Enable this function, and the watch will automatically light up its display when you turn your wrist. Energy saving: the full automatic illuminator only works in the dark.

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

Radio signal receiver
Whether you are in Europe, North America, Central America, China or Japan, this watch can receive the appropriate radio signal to keep your watch "in time".

Solar power
A solar cell is the energy source for this watch.

Indicator for battery power
An indicator shows the current level of the battery.

Moon data display
Based on your current position, in relation to latitude and longitude, the currant moon phases is visible on the dial.

Tide Graph
Tidal movement is graphically displayed on the dial, adjusted for your latitude and longitude position.

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.

Timers - 1/1 min - 24 hours (with auto repeat)
Useful general information: the countdown timer can provide reminders of special and/or repeating events. The timers can also automatically count back from the defined time. Timers can be set in second intervals, up to 24 hours in advance - so it is very useful for reminding about training/medicine.

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.

Snooze function
You can pause the alarm, and it will be reactivated after a few minutes.

Keyboard sounds on/off
The keyboard sounds can be deactivated, without affecting other sounds (alarm, reminders et cetera).

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

Auto calendar
Corrects automatically for months/years with different lengths.

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

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

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

Resin case

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 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.
