This is what overpaying looks like.
Five real eBay sales from the last three months, next to the fair range in the book.
About $5,000 too much, on just five watches. The book costs $39.
Source: eBay sold listings, July to September 2026. The fair range is the middle half of recent sales of original watches. A few top sales are exceptional pieces, and the book shows you how to tell.

Made by the Time Kept channel.
Time Kept is a YouTube channel about vintage watches: flea markets, fakes and what things are really worth. Under almost every video someone asks the same thing. Is this price fair?
This book is the long answer. The prices start from real sold listings, never asking prices, and a new edition comes out every quarter, free for everyone who bought it.
Watch the channel on YouTubeQuestions people ask first.
Where do the prices come from?
From real sales: eBay sold listings, auction results and collector sales. The fair range is the middle half of recent sales of good, original watches. Each page tells you whether its price has been checked against recent sales or is still an estimate for the next edition to confirm.
I’m not a collector. Is it for me?
Yes. Most readers want one or two good watches and don’t want to get stung. It’s written in plain English, in big type, with no jargon you have to look up.
Is it only about Seiko?
No. Japan has the biggest chapter because that’s where the best value is, but the book also covers Swiss, German, Soviet, American, British, French and Italian watches.
What format is it? Is it hard to download?
It’s a 175-page PDF. After you pay, you get a download button on screen and a copy by email. It opens on any phone, tablet or computer and prints fine at home.
How do I get the updates?
Each new edition is emailed every quarter to the address you bought with, at no cost. You can also download the latest version any time from your purchase email.
Is this financial advice?
No. It’s a buyer’s guide to help you pay a fair price. It won’t tell you what to buy to make money, and it isn’t connected to any watch brand.
What if it’s not for me?
Just reply to your Gumroad receipt email within 30 days, or message us through Gumroad, and we’ll refund you in full. No forms, no questions, no hard feelings.
