Hi, yes you can, the watch gives you live results even without a mobile phone and records your values so that they are only synchronised after the race and you can view them on your mobile.
Yes, the Apple Watch SE (2022/2023) with 4G can be used without a nearby iPhone thanks to the integrated cellular connection. However, it requires an eSIM subscription to use this function. So your son can use the watch anywhere there is an available cellular connection as long as he has an eSIM card and the corresponding subscription is activated.
I'm not a professional, but you can put the phone function on the watch face. Then you only need 2 "buttons" (phone symbol and dial number saved in favourites).
However, there are 2 variants of the SE, the one with WLAN requires the mobile to be nearby, the 4G one allows free calls, but there are additional costs.

Hello there. Just have a look at the website. I can't answer that exactly as I don't have an iPhone X. LG

Hi, the sports wristband is included in the two available sizes when you buy it. You can therefore try out whether the size S/M (130-180mm circumference) or M/L (150-200mm) fits better.
Actually "no" unless you clarify this directly with the supplier. There are some who are very tolerant, as long as only the box has been opened.
Good luck and have a Merry Christmas
Ehm, yes, if it's a new product.
If a second-hand product, it is not sealed (indicated)
Otherwise, this Apple Watch has insulation as usual: for taking a shower or swimming it's top :)
Yes, these watches are new. However, you should know that such a watch only runs for about 52 hours at a time and then you have to charge it again. The SE also doesn't have an Always On Display. So most of the time you wear an Apple watch that doesn't show the time, unless you raise your arm.
There are various other models from other manufacturers that have an Always On Display and still run for about 7 to 20 days without recharging. It's not from Apple, but if it's only about fitness, maybe that would be an alternative? The latest Amazfit GTS 4, for example, runs for about 8 to 16 days, has a 3GB music memory (2.3 GB usable):and Bluetooth phone call functions. It can also do fitness with 150 different sports :-).

A charging cradle including cable to USB-C is included, the only thing you need is a USB-C plug (power plug power supply USB-C) - if you don't have this already...
