Ulysse Nardin: To complete the package . . .

UN could replace that soft and easily scratched sapphire crystal with a diamond crystal. Diamond disks up to 2mm thick and 120mm diameter are available, mainly for use in laboratory applications. Could these be adapted to watches? www.diamond-materials.de

Jaeger-LeCoultre: Does a black or ruthenium dial MUT appear smaller than silver?

My local dealer has the MUT with a silver dial only. That means a black or ruthenium dial must be purchased sight unseen, used or old stock through the mail. What's your opinion or recommendation about these three dial colors for the Master Ultra Thin? The silver dial looks small. I'm concerned that

WatchRap (Archive): Oops. Forget Hooke's Law

I retract my invocation of Hooke's Law, since it applies only to a spring in which all the coils remain free throughout the motion.

WatchRap (Archive): One's resources are not fixed

You are correct that I may value a watch highly but not have the money to pay its market price. But it works that way only to a limited extent. There are fabulously rich people that do not buy these watches because they don't care about them. And there are people of modest means that do buy these wa

WatchRap (Archive): Flipping benefits the final purchaser

The highest price the market will bear assures that the item goes to the buyer that values it the most. An "underpriced" item might be purchased by someone that cares little for it. To illustrate with an extreme example, if a valuable painting is underpriced (offered for say $2) it may be purchased
