But when it comes to power efficiency this watch is far better than suunto traverse alpha as battery timing of this watch is much higher than that of casio watch. Another cool aspect is that the crown is made up of mineral which means that you can use it without losing much of the money in your pocket. It is going to last for quite some time and will prove durable and long lasting.
But do note that that you will not get the sensors like alti or barometer with this watch. However the temperature sensing sensor is included in this watch.
