Quick answers

How accurate should a mechanical watch be?
Most modern automatics run between -10 and +10 seconds a day depending on position and wear. Consistency matters more than the raw number: a watch that gains a steady five seconds a day is healthier than one that swings unpredictably.
Do I need to service every five years?
Five years is a manufacturer's default, not a rule. Many movements run well for eight to ten years. Service when timekeeping drifts noticeably, the power reserve drops, the winding feels gritty, or before you expose the watch to water.
Which size actually fits a 6.5" wrist?
Look at lug-to-lug rather than diameter. Under about 47mm lug-to-lug will sit flat on a 6.5-inch wrist; a 38-40mm case in that range usually wears comfortably.
Can I swim with a 100m watch?
Yes for pool and surface swimming, assuming the gaskets and crown are in good order. Leave diving, and hot showers, to a 200m watch with a screw-down crown that has been pressure tested recently.
