I vary it up a bit. My EDC is a Garmin Fenix 5s.
Then I go solar sometimes with my Seiko Excelsior or new Star Wars Citizen, love you honey!
Then I go mechanical from time to time with my Stuhrling or Perigaum automatics.
My fall back for doing rough stuff is of course the unkillable G-Shock.

Exactly. With relativistic time shift, the beats slow down exactly as much as time itself slows down so it doesn't change. It doesn't matter whether it's a mechanical oscillator or vibrations from a quartz crystal....If there are fewer total beats due to traveling at relativist velocities, the total error rate should change relative to more beats in the earth frame.
Obviously, yes, within their own reference from frame its moot.
The short answer is no. The difference in accuracy is only about 4:1. That is, the best mechanical watches are +/- 2 sec per day, quartz around +/- 0.5. That's plus or minus, they can speed up or slow down on any given day, so I don't see how relativity could play a role.... Does a purely mechanical watch drift more in 1 day* than a quartz watch drifts in 1 year? ...

One nice thing about mechanicals is that they should still work after a powerful EMP. So if somebody lights off a nuke in the upper atmosphere, those of us with mechanical watches will still be able to keep time during the aftermath.
Some day I want to get a watch with bronze and meteorite elements. One to honor history, the first metal (actually, alloy) humans mastered. The other to wear a piece of the distant universe.
Something like this, but less blingy: https://zeloswatches.com/collections/mako/products/mako-v3-300m-bronze-meteorite

EMP could affect mechanical watches if the movement gets magnetized. Some mechanical watches are effectively faraday cages - Rolex Milgauss or the Omega 53 6B/542 watches that were used by RAF.

True, also some Ball watches are designed to be less affected by magnetic fields. Either type (quartz or mechanical) can be shielded against EMP. However, an unshielded mechanical watch is more robust against EMP than an unshielded quartz watch. The quartz will be destroyed (at least its circuit will be), while the mechanical will still run. It will be less accurate until it's demagnetized.EMP could affect mechanical watches if the movement gets magnetized.

The Bulova 23 "USA 1956":
just like me!
B-day gift to myself this year.
Don't like numerals nor date on dial; not even second hands [didn't find a '56 w/o; though at least it doesn't have a separate dial for seconds either].
Sunburst dial was a bonus.
Luminous hands no longer glow...
just like me as well!!
Related question: can you demagnetize a watch with a regular old wand-style tape deck demagnetizer?
I was thinking about Spring Drive...Yes, they [spring drive] are different.
Which is probably why mine broke -- generation 1 of a new technology.
I like nicely made engineering so looked into Grand Seiko, when I read how spring drive works a while ago I just thought "why bother?".I was thinking about Spring Drive...
Nothing in the movement ever reverses direction or stops. Everything is continually spinning, even the balance wheel. This should promote longevity because it should keep all lubricated bearings and pivots hydrodynamic (due to relative motion & film strength). That means no physical contact. In contrast, a conventional balance wheel and hairspring reverses direction several times each second. This means it is momentarily stopped, which causes physical contact because lube film strength relies on relative motion. Like waterskis hold you up only when moving; when the boat stops you sink back into the water.
Since everything in Spring Drive is always rotating in the same direction, never slowing or stopping, it should last pretty much forever. And the perfectly smooth second hand sweep is a natural result of this. It's a brilliant idea, powering a quartz watch by a mechanical coil spring, having no battery or capacitor.
PS: explanation how it works, for those who are curious. At 4:30 he explains the piezoelectric effect. At 7:50 he starts the spring drive specific part.
