Grand Auctions is proud to be offering for auction this eye-catching watch, a modern version of a distinctive timepiece originally created in The Roaring Twenties when wristwatches were first becoming popular. Think Bauhaus and Art Deco, think jazz music, think post-war North American affluence, this is a watch of its time that still packs huge appeal, even (and especially) in today’s digital era.

In the news recently was the story of a 26.27 carat cushion cut diamond originally purchased in a Sunday sale in the 1980s for only £10. The owner always presumed it was paste and enjoyed wearing it for 30 years before finally discovering its true worth after visiting a jeweller’s. It sold for the incredible hammer price of £540,000 at Sotheby’s, London on 7th June! In this blog we take a quick look back at a few other, notable car boot sale finds.

Although not technically a complication, the tourbillon is certainly worthy of inclusion under the genre. It is a movement which places the escapement and the balance wheel of a watch inside a rotating cage. The word tourbillon refers to the vortex created by whirlwinds or whirlpools, an image evoked by the movement of the rotating cage. Such a design is intended to negate the effects of gravity when the timepiece (and therefore the escapement) remains too long in the vertical position. In this article we take a brief look at the history and design of the tourbillon.

Calendar watches can be very simple or incredibly complicated depending on just how much information they provide and how often they need manual adjustment to retain accuracy. Some of the most expensive watches in the world feature calendar complications and can sell at auction for many £millions. In this article we look at the different types of calendar complication.

In this article, part of a series about watches, we take a look at the repeater complication. A repeater is a watch that is able to chime the time on demand at the press of a button. Dating back to the 17th century, in an age before artificial illumination was widespread, this function could be extremely useful. Now, it is valued more as an example of fine horology expertise and collected by enthusiasts.

In this new series of articles about watches, we take a look at various watch ‘complications’, or features of a watch above and beyond the standard time-telling function. Complications can be relatively simple, such as adding date functionality, or extremely complex, such as displaying equation of time, the discrepancy between apparent and mean solar time. In this first article we take a look at the chronograph complication.
