Fucking Time Propagation (lemm.ee)

Just bought the GWM 5610U-1C. It was a tough decision choosing between the DW5600 and this, ended up choosing this because the atomic time keeping is cool.

However, I'm a tad annoyed that the time doesn't perfectly match with time.gov and time.is since the atomic sync doesn't account for time propagation, so there's like a fraction of a second delay that's noticeable. Other than that, the watch is fantastic and has most features I would want. (I wish it had barometer and altimeter stuff, maybe even compass, and dive rated so I can press buttons underwater)

The speed of light is fast, like stupid fast.

Some napkin math puts the travel time from Denver to DC at 1/100 of a second which for a human should be unnoticeable.

I doubt you could tell the difference between two watches with that difference.

I do tell the difference though, which in theory, it should be so close that I would miss it, but I swear to you there's a difference. Maybe I will take a video when I get the chance.
