Most collectors get lost in the marketing story, the waitlist, or the logo. Aeternus is for people who want to know what is actually ticking, and what a listing is actually worth.

  1. Research. Tenue Score. How much mechanical watch is in this watch.
  2. Decide. Ask. What this listing is actually worth, in private.
  3. Learn. Writing. The Long Sweep. The Gospel of Horology.

Research

Tenue Score answers one question. How much watch is this? You send a brand, a model, and a reference. You get a reading back, 0 to 100. Quartz is not scored. Price is never on the sheet.

We look at the movement and how it is tested. The case, the clasp, the crystal. Whether the watch can be kept alive. Hand-finishing is described when it is real. It is not poured into the number.

Decide

Ask is for people who already buy and sell. You get a market range, a cash buy-back, fees, the most you should pay, the risk, and a call: buy, caution, or avoid. Ask may show a Tenue Score so you can see the substance. It may never write a dollar amount back into that score.

Learn

The Long Sweep is the video program. Heath Jackson hosts. Episode 0 teaches the score. Episode 1 puts two watches on the sheet.

The writing is long and short. The Gospel of Horology is a book about what a watch means. It does not score watches and it does not price listings. There are no photographs of watches. The sample is the Foreword.

Score the watch. Price the listing. Do not mix the two.
