Lo unico es que no me gusto que es menos voluminoso que su antesesor, este modelo es mas compactoFirst-time buyer of a Samsung watch - the high-end fancy watches have been relegated to the jewelry box.I didn't think I would like a smart watch. Had one before when they first come out many years ago with the very first samsung watch. It's just like a mini cell phone on your wrist! Pretty much has most of the same apps, cell phone feature works great and overall I really like it especially with the rotating dial.Love the watch, its everything I need a smart watch definitely would change out the band though.To all the ones saying the GW4 has crappy battery life: CALM DOWN! Give it a couple of weeks. I was dissapointed at first , I was getting only 14 hours of battery lilfe but then I saw the recommendation on all the GW4 forums saying that I should let it learn your usage and calibrate. After 2 weeks I was getting 54 hours battery life and still do.Let me be clear. This is not the best sports tracking device. Get a dedicated sports watch like Garmin if you are obsessed with accurate steps or exercise tracking. Dont get me wrong, the GW4 will still give you a range with 20% of actual numbers so its useful if you are not that picky and you can still track your overall progress. Still , I use it for running and distance tracking is spot on.What this watch excels on is customization. You can change from casual to sports to formal watch in seconds, I am attaching some samples. There are TONS of accesories for it. The screen is beautiful, battery is good, its fast and smooth and apps are getting better and more available each month.I love mine more than I do my Apple Watch as I dont want another rectangle in my life, I want a proper, round watch.Battery life sucks.Cool functions but too much razzle dazzle.I miss my old watch.Looks like a man's watch . It is huge and super thick.the appearance of galaxy watch 4 classic is fashion, sharp and decent. comfortablity of wearing is also no complaint. the only drawback is the battery. However if "always on display" is not on, and for reulgular usage, it can last for almost 2 days, so basically if you can do recharge daily in the evening after a while day of usage, I don't see reasons of not buying it. functions are also efficient。Buen reloj, lástima que algunas funciones como el electrocardiograma no funciona en México segun Samsung porque le secretaria de Salud no lo ha autorizado.La apacidad de la batería como en toda la línea de Samsung galaxy watch es mala, aunque mejora mucho en el de 46 mm que dura hasta 2 días de uso más o menos intenso, la versión de 42 mm de este mismo reloj no me duraba ni 1 día.No puedes configurar México como país al iniciar el reloj me imagino que es por las limitantes que tienen algunas funciones de salud aunque no afecta su funcionamiento poniendo otro país en mi caso escogí Colombia.Excelente que ya se tenga Wear Os en estas versiones watch 4 esto hace que todas las app de Google funcionen perfectamente y sean fluidas sin tener que usar por ejemplo una app de navegación en conjunto con el reloj (galaxy watch, frontier, etc), es decir Google maps ya funciona directamente en el reloj.En resumen debe ser una de las mejores 5 opciones en smart watches y cuando puedan funcionar las opciones de salud bloqueadas sería un competidor muy a la par del Apple watch a un tercio del precio del de Apple.Es el mejor smartwatch en ese rango de precios, lo valeEn su configuración no aparece México pero no es que sea necesario, solo con escoger un país de habla hispana y tener un celular compatible es suficiente, funciona de maravillaEs el mejorTODO MUY BIEN
