Given the current penchant for smartphone GPS apps such as RunKeeper and Nike+ Running that record exactly where you've been on a run, the Suunto Core's habit of logging your altitude gains and losses - and displaying them on a graph - will likely appeal to most users. It works for seven days, which should cover a week's worth of skiing, walking or mountain ascents.

This watch also has a built-in thermometer that can be useful in many situations. For an accurate measurement, it is advisable to remove the watch from your wrist at least 15 minutes before measuring the actual environmental temperature. Elsewhere, there are three alarms (to let you know when you've ascended, say, 100m), a stopwatch and a timer, as well as a thermometer. As you set the watch up, if you tell it where you are it will show sunrise and sunset times, too. Verdict This Garmin MARQ watch is also equipped with an array of smart functions. These include a heart monitoring app, a hydration detection function, wireless connectivity to Bluetooth and Wifi, and ClimbPro, an app that gives you instant data on the climbs and gradients that await you on your route. All of these can be viewed on the watch’s colourful digital dial, which showcases legible numerals in red and blue hues along with blunt white hands for the time display.

Lastly, the compass mode is a quite straightforward function that allows the use of the timepiece as a digital compass.

Buen reloj para alpinismo. El altímetro es muy preciso y marca metro a metro no como mi anterior suunto vector amarillo que marcaba cada cinco metros. La batería dura mucho (la mía ya dos años lleva puesta) los menús son súper fácil acceder a ellos, la función de hora dual es muy práctica cuando viajas a otro país. (Así sabes cuándo llamar por teléfono jeje) la brújula también va muy bien. En general se usa mucho más fácil e intuitivo que mi viejo vector. En lo que falla es que en el modelo de pantalla negra (el mío) los caracteres se ven poco en interiores pero en el exterior que es en definitiva para lo que se ha diseñado, se ven muy bien hasta por la noche. Además tiene una estética muy atractiva, cuando no estás en la montaña sigue valiendo como reloj de vestir. Hodinky Core ukazují hloubku (do 10m) a čas strávený pod vodou. Bezpečí před nechtěným stiskem jistí zámek tlačítek. Hodinky Suunto Core nejsou potápěčské hodinky, jsou vhodné například pro šnorchování a pro plavání.The Suunto Core has a clean and straightforward digital display, with a dark aesthetic that can go well with any style or outfit. Its interface is very user-friendly, with a large screen that bears pronounced letters and numerals for better legibility. Its different modes and functions are also all clearly labelled, which makes it easier to navigate this watch. One weakness of the Suunto Core, however, is that the layer of mineral glass used to protect the digital dial is quite reflective. As a result, when the watch is exposed to high-intensity light, this can cause light glares that distort the watch face and make it harder to read. Similar to its competition, the Core has a compass with adjustable declination. You can set it to help you record and follow compass bearings. In all the models we tested, if you are doing more serious off-trail travel we wouldn't bring this as your only compass, but it's fine for people who just need it for a general point of reference. Other cool features Weather changes can be predicted via the barometer. The weather trend indicator shows data from the barometer recorded over the past three and six hours. The temperature range that can be measured is from -20 to 60 degrees Celsius.
