Until his death in 2011, George Daniels was one of the most famous and celebrated horologists in the world. Famed for his innovations, most notably the groundbreaking co-axial escapement, he is currently the only horologist to have received both an MBE and a CBE.
He was also revered as the only watchmaker who could create every component of a watch by hand.
Daniels was fascinated at an early age by the workings of a damaged pocket watch and resolved to learn how to repair it.
By the time he joined the army at age 18 (in 1944, with WWII in its last throes) he was offering to do repairs for his fellow soldiers.
Later he was introduced to Breguet by his friend Sam Clutton and became fascinated with the great innovator's work. Daniels concentrated on the repair and restoration of Breguet watches for many years and wrote the leading work on them, which was published in 1975.
Daniels's first watch was sold to Sam Clutton for £2,000 in 1970 and it is understood that he bought it back from Clutton five years later for £8,000. It sold recently at an auction in the United States for $285,000.
Of course, a devotion to watchmaking comes hand in hand with a stunning collection, and Daniels' was truly awe-inspiring.
An impressive 130 watches and timepieces, representing the great makers of the 17th, 18th and 19th Centuries, went under hammer at Sotheby's in November 2012.
Almost every major figure in the watch collecting industry was present, if not to bid then simply for the sheer spectacle.
With standing room only declared in the London showroom, Daniels' watches realised a total £13.2m ($21.1m), topping the sale's high estimate of £5.7m ($9.2m) by 128%. Proceeds were donated to the George Daniels Educational Trust.
The star of the show was Daniels' own unique Space Travellers Watch, an 18k yellow gold pocket watch that sold for £1.3m ($2m).
Designed by Daniels to commemorate the first Moon landing, the piece offers "everything you'd need on a watch if you were travelling through space", including an independent double-wheel escapement, mean-solar and sidereal time, age and phase of the Moon and equation of time indications.
Not to mention a breathtaking aesthetic that rivals the finest the market has seen.
Also starring in Daniels' collection was a silver-mounted ebony clock made by esteemed restoration-era watchmaker Joseph Knibb, which made £1.2m ($1.8m). The magnificent clock was given to Thomas Beckett by King George III for his loyal service as surgeon to the Grenadier Guards from 1794.
Daniels' fine taste in watches and his eye for the finest quality was also reflected in his classic car collection, which was brought to auction through Bonhams in June 2012 at the Goodwood Festival of Speed.
