Watch buying guides

A handful of specs decide almost everything about living with a watch. These guides take them one at a time — every figure computed from the 128 watches in the database, so nothing here is an opinion wearing a fact's clothes.

What size watch actually fits your wrist?

Case diameter is the headline number, but lug-to-lug length decides whether a watch overhangs your wrist. Sizes here run 34–53 mm with 40 mm the most common. Style shifts the answer more than your wrist does.

Automatic vs quartz: which movement should you actually buy?

Quartz is more accurate, cheaper and nearly maintenance-free. Automatic is chosen for the mechanism — no battery, a sweeping hand, serviceable forever. Neither is "better"; they optimise for different things. This database skews mechanical: 90 of 128 are automatic.

Sapphire vs mineral vs acrylic: which watch crystal matters?

Sapphire resists scratches but is brittle. Acrylic scratches easily and polishes out in minutes. Mineral and Hardlex sit between. Sapphire is no longer a premium signal — 83 of 128 watches here already have it, so expect it rather than pay for it.

Can you swim with a 100m watch? What the ratings actually mean

Water-resistance figures are static pressure tests, not swimming depths. 30 m means handwashing and rain. 100 m is the usual swimming threshold. Only a watch marked DIVER'S has met the separate ISO 6425 dive standard. 95 of 128 watches here reach 100 m or more.

How much should you spend on your first good watch?

Less than you expect. The entry tier here holds 21 watches across 5 styles, 0 with sapphire and 12 rated for swimming. Nothing you need is above it — price buys finishing and mechanism, never accuracy.
