User level: Level 1 (4 points)My Apple Watch randomly restarted 2 times today. It shows a black screen, then the Apple logo appears and disappears continuously until it boots after 2- 3 minutes. I got it today, new, from the Apple Store. Could it be because the temperature is too cold? Battery health is 100%; the battery is fully charged too.

I've had an apple watch 4 and now a 10 and never experienced what you describe
their specs say
Environmental Requirements
Operating temperature:
32° to 95° F (0° to 35° C)
Nonoperating storage temperature:
–4° to 113° F (–20° to 45° C)
Relative humidity:
5% to 90% noncondensing
Operating altitude:
0 feet to 10,000 feet (0m to 3000m)
Apple Watch Series 12 - Technical Specifications - Apple
if you do not expose it to out of those operational temps then if it was me then I would bring it in for review.

My issues with this problem with the new 12 started after 27.0.1 was installed. Re-paired the 12 and still happening multiple times a day. Battery drops significantly (3%) after reboot.
