I'd agree with a thermal compensated quartz (e.g. Breitling's super quartz) stay on time rather well.Wlson_smyth wrote:...a mechanicals accuracy will vary depending on your activity, angle the watch is worn at or left on bedside table at night so accuracy will always vary. A quartz is almost unaffected by such things...
However a normal quartz is affected by such things as temperature variations.
What may be a surprise is a quartz worn on the wrist effectively maintains a sort of constant temperature. So it stays quite accurate. It's when removed at put on the nightstand, bathroom basin, etc that it can vary.
I like my automatics but long ago I stopped being sniffy at quartz. It's just another variation and the actual 'complications' that can be added would be undreamed of in the mechanical world.
Indeed after looking into how the likes of Elliot Brown put their quartz together for shock protection etc. then they're good all round kit. The attention to detail on cases and protection would explain my problem with quartz in that if the basic mechanism cost peanuts (ok, let's say ballpark $10 for non-COSC) how come the watches cost several hundred?
FWIW I have a radio-controlled quartz watch in the box for setting my autos when I'm not near the internet and can use the likes of time.is.
