TIMEX EXPEDITION E COMPASS WATCHES. A SIMPLE REVIEW

Here’s what Timex have to say about their E Compass family of Epedition watches -

T49541 2The Expedition E-Compass watches employ a sophisticated, miniaturised sensor that detects the earth’s magnetic field with a press of a button.  Precise to within 10 degress the Expedition Electronic Compass watch allows the user to easily adjust for regional variation between magnetic and true north.

From the Timex Expedition range these E Compass quartz watches are robust in their build quality and are aimed at the outdoor wearer. The watch case itself is made from stainless steel or Titanium along with quality water resistant leather straps. The style is simple, solid and includes a static fluted bezel. The case back is polished stainless steel. Dimensions are #  42mm diameter excluding the crowns and buttons x 11mm deep. 

Time is told by three hands, Hour, Minute and Seconds. The hour and minute hands are illuminous and show-up well in the dark.  The second hand is a slim red design which help to give a sporty feel to the dial.  The dial itself  comes in a variety of attractive colours.  24 hour markers are also present.  A quick-set date widow is at the  4 o’clock position. The glass cover is flush fitting to avoid scratches and scrapes.

The most important part of the E Compass range is its compass.  The Electronic compass is accurate to within 10 degrees and includes a Declination Adjustment Scale.  AT49201 press of the compass button and the 4th Compass Hand points directly north.  To save power the compass works for approx 15-20 seconds and then with an audible signal returns to its resting place at 12 o’clock.  The 15-20 seconds is ample time to read North or to show the direction you wish to go in or are coming from.  The lower crown on the watch case revolves the inner compass marked ring, which means once you point the N (North) marker to the compass point all directions are identified without you having to move round pointing your arm and wrist to North.  Although the compass is Electronic and not Mechanical its still important to use the watch fairly level to get an accurate readout.  During the compass operation the second hand moves at 2 second intervals which appears to send most of the available power to the compass mode without stopping the second hand all together.

T49551 2The Timex Expedition E Compass range of watches have the added bonus of being 100m water resistant and include the Indiglo Night Lite.  The Timex Indiglo Night Lite is reviewed in this blog site and is activated by a press of the main watch crown which saves the need to have a futher button.  The Indiglo Night Lite illuminates the whole dial and works very well.  The watch is finished off with a quality padded and stitched water resistant leather strap and matching steel buckle. The strap appears robust enough to cope outdoors but offer the wearer real comfort.

Overall, the Timex Epedition E Compass range of watches offer fantastic value for money particularly considering the standard of the electronic compass fitted and the general build quality.  MyWatchShop.co.uk has no hesitation in recommending the E Compass range.

Citizen Eco Drive Power Generating and Storage system.

eco-drive-diagram

The Citizen Eco Drive power system has been available since 1995 and has proven to be very successful for the Citizen Watch Co. In essence Eco Drive watches are Solar or Light powered timepieces.

Being highly technically advanced but at the same time very simple. A Solar conversion panel and energy cell are the power provider for these Quartz Watches. Light, both natural and artificial is converted into electrical energy by an extremely thin disc of Silicone located under the watch dial. The electrical energy is then stored in a Titanium Lithium-ion energy storage cell.

Depending on the model, once fully charged Eco Drive watches, if left in the dark will continue to tell accurate time from a matter of months to up to 5 years if it is the model with energy saving functions. Models with the energy saving modes will shut down if left in the dark, with the hands being still but the quartz movement continues to keep time. Once brought out into the light the watch wakes up and the hands return to telling the correct time.

Many differant watch styles and functions are now available with the Eco Drive system due to an increase in efficiency. Eco Drive Chronographs, Alarm, Divers, Moon Phase, Retrograde, Repeater and even small Ladies watches are available. The Eco Drive Divers watches have a clear following as Divers watches need to be pressure tested when a battery is changed. As the advanced Titanium Lithium-ion energy cell usually last beyond ten years and often for the life of the watch the expensive pressure tests can be avoided.

The Eco Drive system has been very successful for Citizen so much so they seem to be offering more models with the technology rather than normal quartz watches. The system certainly appears to be well regarded and reliable.
