Warning to change the battery: if we want to continue to dive with the watch (which contains a depth operated down to -10 M) have to buy Suunto kit including a battery and a new seal. If you do not dive with no need to change the gasket (say no to changing the battery, but after a battery change). If you do not change the joint, you have to buy the silicone lubricant, put some on the tip of his finger, and spread it over the seal in the form of a thin film before putting the seal in the shows (see the Youtube channel of the Suunto brand, they have a video that shows how changing a battery on this model).
Never touch the replacement battery with hands, as they are conductive and will lose several months of load to the battery. We must therefore handle the battery with a latex glove or a piece of paper towel to install it in the watch. When removing the old, use a non metallic object such as a wooden toothpick, and especially anything that is not metal (short circuit in the watch guaranteed otherwise that will be damaged).
Very nice, excellent evolution compared to Vector module. The Vector module can suffer much more damage and still function, so if you plan on climbing or shocks, Vector will be more solid. For mountain climbing beyond 2,000 meters, I would take the Core rather than Vector. A replacement battery crept into a corner in case.
She is beautiful, especially in black display. I never had the display reading concern, and you can adjust the contrast on this model (you can not do it on a Vector). On the Internet there is the doc to enter the maintenance menu, which allows you to change the contrast beyond the requirement of the doc needed.
If you do not handle the replacement battery with a direct contact with the skin of the fingers, and use a small toothpick to remove the old, do not worry. It is recommended to change the battery for a new one prior to a shipment rather than having to play numb fingers aloft if the battery comes to weaken.
A very good change compared to the Vector, but slightly weaker against shocks. The screen of a Vector is scratched plastic it more cash, by against a Vector will after 5 or 10 years the well scratched although functional screen. The Core has a mineral screen that does not scratch easily: even direct impact above leave no scratches. But experience, I would not do him not suffer the abuse that I was able to subject my Vector (throw me to the ground, the watch tapping the floor with me or climb trees with bare hands and sometimes the shows rubbing everywhere scratching plastic screen of the Vector).
Comfortable strap, which has been improved there is little time at the small room that holds the tongue; it was too hard to remove or move, and they corrected planing half of the recess that rubs on the strap tongue .
Protective screens found on Amazon or Ebay very easily that will stick on the screen if you fear for the latter scratches. But you will not have this concern with the Vector. For my part, I think we have a Vector and Core. The Vector version HR (Heart Rate) to monitor their heart level and the work between 70 and 90% of its maximum level to increase its cardiac capacity, and we attach Core on his bag depending altimeter, set from a point of known altitude, storm alarm activated and that this function is used, the altimeter and the sunrise / sunset in mountain hiking. The Core is particularly at ease in the mountains.
