Product bonus
Create your own training to split your efforts. You can define: - your warm up time (WARM UP) - your acceleration / fast exercises time (RUN) - your recovery / slow exercises time (REST) - the number of RUN accelerations + REST recovery repeats in a series (REPEAT) - the number of RUN+REST series (SERIE) - your rest time in-between 2 series of exercises (BREAK) - your cool down / stretching time (COOL).
Progressing, losing weight and improving your stamina
If you want to lose weight, improve your performance and make progress, it is essential to split your efforts during your workout. This means that you will alternate fast exercise and slow exercise. It will make your activity less monotonous!
Example of customized training
Settings for a 50 minute workout: WARM UP: 15 minutes RUN: 30 seconds / REST: 30 seconds REPEAT: 6 SERIE: 2 BREAK: 8 minutes Go through a first sequence (SERIE 1) of 6 accelerations (30s each) and 6 recoveries (30s each) then an 8-minute BREAK in between these 2 sequences, then a second sequence (SERIE 2) of 6 accelerations (30s each) and 6 recoveries (30s each). COOL: 15 minutes to finish your session and stretch
Dual time zone
For adventurer athletes, the W900M includes 2 times zones. You can see your original time and the time of the location you're in.
Top-range materials
In this watch, we used only high-end, high-performance materials to accommodate your training and everyday life needs: steel and ABS case for added resistance and enhanced finish quality, and mineral glass for scratch resistance. It is water resistant for all water sports (10ATM / 100 m), the buttons were designed to be pressed underwater without affecting the watch's watertightness. It is Geonaute's top-range watch.

Nice watch. Works well. Interval countdown timer useful for running.
Well built, nice-looking watch with great features

I had used Timex Ironman triathlon watches for years, but they kept falling apart after around 18 months. I bought this watch around two years ago and still looking great!
