Common questions

How do you compare two watches?

On the specs that actually differ, not the marketing. Every head-to-head here puts movement, water resistance, case diameter and crystal side by side, then says which one to buy and why. 346 pairs are covered, chosen because they are watches people genuinely cross-shop — same style, similar budget, different on the specs.

Which watch specs matter most when comparing?

Movement type sets the ownership experience (automatic needs wearing or winding, quartz needs a battery, solar needs light). Water resistance is a static pressure rating, not a swimming depth — 30 m means rain and handwashing, 100 m is the usual swimming threshold. Case diameter and lug-to-lug decide whether it fits your wrist. Crystal decides how it survives a decade.

How many watch comparisons does WatchSpecDB cover?

346, grouped by style: dive, field and explorer, dress, pilot, GMT and travel, chronograph, and everyday. Each pair is two watches at a similar price in the same category, which is the situation where the spec sheet actually decides it.
