By Passion Asset Advisory Watch Desk.

The Passion Asset Advisory journal publishes cost guides, collector references, market methods, and process explainers. Each page names its sources, separates asking prices from transactions, and states a review date. Passion Asset Advisory accepts no payment or affiliate commission for editorial rankings.

References & cost guides

What do these assets actually cost?

These guides give indicative purchase ranges, realistic annual budgets and the rules that the industry uses. They cover jets, yachts, Birkins, leathers and watch auction records. Every figure is dated and qualified. It frames a decision but does not price your specific asset. That work needs a mandate.

Use these decision guides to compare specialist routes, prepare an asset for review and distinguish a neutral reference guide from an accepted collector-watch engagement.

Comparisons

Which one should you buy?

These reference comparisons cover marques and models across jets, cars, yachts and watches. They do not identify office clients or confirm available services. Each comparison explains the main differences, then gives a specification table and practical selection criteria.

About the Journal

Where do the Journal's figures come from?

Purchase and operating ranges are indicative market knowledge as of the date on each article. They frame decisions but do not price assets. Auction results are reported as published by the auction houses. Every article carries its update date. Prices, rules of thumb and other changing facts are dated and qualified.

What does the Passion Asset Advisory Journal cover?

The Passion Asset Advisory Journal publishes plain-language research on physical assets, source evidence and transaction questions. Topics include jet and yacht running costs, Hermès price and rarity guides, watch-market notes and private brokerage. The category guides do not establish active non-watch services. Figures are qualified, no content uses affiliate links, and usefulness comes first.

Do the guides establish today’s market value?

No. A guide records evidence from its stated observation dates. An auction result, advertised asking price and estimate have different meanings. To value a specific watch, match its reference, condition and documents to relevant evidence and ask for a dated assessment.

Why does a brokerage publish its knowledge?

Because informed clients make better mandates. The Journal explains evidence, costs and role distinctions before a reader needs an asset-specific review. Publishing this information removes unnecessary mystery and makes intermediary economics easier to assess.
