A look at the new SKX line: https://www.youtube.com/watch?v=RWYT3cDPj50
The part of that video where he was checking the accuracy got me thinking - Considering the delicate metal parts of a movement and oil used for lubrication, does the temperature affect timekeeping? If so, would a change of ~20-30c between Winter and Summer have any meaningful effect?

I'll be honest and say I didn't see that far into the video. I would say that temperature would affect any movement though. Bark and Jack's most recent video has some great info on the Seiko GF85 movement and how it's regulated to check the temperature hundreds of times a day and self adjust to keep the timing as accurate as possible. All the mechanical parts of the piece are sealed in an air tight cabin to ensure that lubricant does not dry up and the moving parts are kept in optimum condition. This apparently ensure servicing is not required for around 50 years even though you still have to change the battery! Based on this though I would yes though.
Edit: Just checked and it's temperature fluctuations regarding the quartz crystal so probably ignore all that! I guess that if it's cold enough the parts may expand or contract but not sure if that would have a big affect or not.

I like the look more than I thought I would but feel it gives it a more dress watch look and that it would have been better if they'd moved the crown to the standard position but obviously being a huge part of the SKX and Seiko dive watch makeup, that won't happen.
