Guides

Buying guides

The reasoning behind every pick on this site. Start with what a watch costs to keep — it is the number nobody else publishes.

The roundups on this site tell you what to buy. These pages tell you why, and they are where the actual work is. If you only read one, read what a watch costs to keep — it is the arithmetic that none of the ten competitor pages we analyzed before building this site publishes at all.

Start with these two

  • [What it costs to keep a watch running](/guides/cost-of-ownership). Purchase price plus the manufacturer's published service interval and published service price, computed over ten and twenty years, with every input cited. It changes which watch is cheapest, and not in the direction you would guess.
  • [Watches that last a lifetime](/guides/watches-that-last-a-lifetime). The criteria first, then the picks. Serviceability, parts availability, crystal, water resistance, warranty and strap standardization — in that order, because that is the order they fail in.

Then the material questions

Three specifications account for most of the difference between a watch that looks good in 2046 and one that does not, and all three are decided at the point of purchase and never afterwards: the crystal, the case metal, and the water resistance rating. There is a guide for each, and they are short because the answers are not complicated once somebody states them plainly.

How these guides are written

Every factual claim on these pages is traceable to a manufacturer document, a published ISO standard or a named source, and each page lists its sources at the bottom. Where a figure could not be sourced, the page says "not published by the manufacturer" rather than filling the gap with something plausible.

That is a slower way to write and it produces shorter guides than the category norm. It also means you can check us, which is the entire basis on which we ask you to believe anything here. The method sets out exactly what we do and do not do.

Questions people actually ask

Which guide should I read first?

Cost of ownership, if you are choosing between a mechanical and a quartz watch — it is the arithmetic that decides it. Watches that last a lifetime, if you have already decided and want to know what to look for.

Do these guides recommend specific watches?

Several do, and they carry picks with buy links where the watch is available. The material guides — crystals, metals, water resistance — mostly do not, because the answer is a principle rather than a product.

How often are these updated?

Cost of ownership every six months, or immediately if a manufacturer changes service pricing. The material and comparison guides every twelve months. A page's date changes only when its content actually changes.
