Longines Celebrates 100 Years of Dual Time Zone Watches with the Spirit Zulu Time 1925

Longines continues to expand their Zulu Time collection with the new Longines Spirit Zulu Time 1925. Never one to shy away from an anniversary, the latest version of the Longines travel watch celebrates the 100th anniversary of the brand’s first watch to display dual time zones. These early dual time zone watches featured colorful representations of maritime flags referencing the letter “Z”, a nod to the time at the zero meridian in Greenwich. The “Z” designation ultimately led to pilots referencing “Zulu time” when referring to time at the zero meridian, an important concept when traveling across time zones. The modern renditions of the Zulu Time watches are completely distinct from their historical counterparts in terms of their design and aesthetics, but for Longines their intent seems to be to recreate the adventurous spirit of those watches in a modern package. All of the Zulu Time watches to this point have straddled the line between a clear vintage inspiration and contemporary design tropes, resulting in watches that have a classic everyday appeal.  Last year, I reviewed the Spirit Zulu Time Titanium, which simply by virtue of the material used felt like the most contemporary iteration of the Zulu Time yet. I really enjoyed my time with that watch and felt that Longines really nailed the proportions, with a case just under 40mm that was also not too long from lug to lug. The new 1925 version of the Zulu Time is perhaps best thought of as the inverse o...

The Greatest Collectors of All Time: Courtenay Adrian Ilbert – A Passionate and Meticulous Collector with an Extraordinary Dedication to Horology

“The Greatest Collectors of All Time” is a series of features that will look at what drives a collector to collect and how they go about seeking out items they want for their collections. Here we look back through time to highlight the greatest horological collectors and showcase their particular area and passion for collecting. Courtenay Adrian Ilbert (1888–1956) was one of the most notable horological collectors of all time. He had the wealth, passion and enthusiasm that enabled him to amass an immense and varied collection. This was at a formative time when many unrecognized horological gems were coming to the market due to a developing appreciation of technical horology and world circumstances. His collection, known as the Ilbert Collection, included an impressive array of timepieces from the 16th century to his time, featuring some of the rarest and most exquisite watches, clocks, and horological instruments. Professionally, Ilbert was an engineer, and his technical knowledge informed his horological expertise. His engineering insights helped him appreciate the intricate workings of the timepieces he collected and restored. He was an extremely fine craftsman taking infinite patience in the matter of restoration and repair. Courtenay Adrian Ilbert (1888–1956) Born in Reading, Berkshire during the Victorian era, on the 22nd April 1888, his family background provided him with the stability and resources to pursue an excellent education. From a young age, Ilbert ...

The Greatest Horological Inventions of All Time: Why George Daniels’ Co-Axial Escapement Revolutionised Mechanical Watchmaking

Editor’s Note: Today, the final installment of The Greatest Horological Inventions of All Time. Here, Andrew Canter examines the story behind the co-axial escapement, invented by George Daniels, industrialized by Omega, and now considered one of the great watchmaking innovations of all time.  You can find more of Andrew’s work at the Mr. Watchmaster website here. George Daniels (1926 – 2011) was raised in London in poverty. Aged five, he pried open his family’s alarm clock and realised that it was a metaphor for his life – always moving inexorably onwards, but without outside assistance. He was determined to learn horology, despite his parents’ opposition. He was conscripted into military service in 1944 which unleashed his innate mechanical skills, and following the end of the war, he studied horology, while repairing watches in North London.  He gained access to the work of the greatest watchmakers, particularly Abraham-Louis Breguet, through a meeting with a collector, and when it seemed that quartz technology would overwhelm traditional watchmaking, Daniels ensured this would not come to fruition. He made a series of increasingly ingenious mechanical watches, heavily influenced by Breguet, teaching himself to make every part, now referred to as the ‘Daniels Method’. Essentially, he devised a virtually oil-free escapement – the now iconic co-axial escapement – which was later mass-produced by Omega. It was anything but an easy journey, but George D...

The Greatest Horological Inventions of All Time: Why the Atomic Clock Was Invented

Editor’s Note: Today, we bring you the third installment in Andrew Canter’s series, The Greatest Horological Inventions of All Time. Today, Andrew examines the history of atomic timekeeping, from its earliest conception, to its potential future. Atomic timekeeping and atomic clocks are often misunderstood, but they form a framework for modern timekeeping standards that is, ultimately, indispensable.  You can find more of Andrew’s work at the Mr. Watchmaster website here. “A more universal unit of time might be found by taking the periodic time of vibration of the particular kind of light whose wavelength is the unit of length.” James Clerk Maxwell, Scottish Physicist from his Treatise on Electricity and Magnetism dated 1873 Cover page of James C. Maxwell’s A Treatise on Electricity and Magnetism, published in 1873. It was way back in 1900 that the German physicist Max Planck suggested that the energy of an atomic oscillator is quantised. Albert Einstein extended this concept in 1905, explaining that electromagnetic radiation is localised in packets, later referred to as photons, of frequency and energy. This was the beginning of the journey that led to the invention of the Atomic Clock. How does an Atomic Clock Work An atomic clock is a type of clock that uses certain resonance frequencies of atoms to keep time with extreme accuracy. The electronic components of atomic clocks are regulated by the frequency of microwave electromagnetic radiation. Only when t...

Editorial: Memorable Moments at IAMWATCH

The first large scale watch fair I attended as Tempus in Singapore in 2004. A teenager then, I was fairly new to watches and found everything endlessly interesting. History never repeats but it rhymes, as the saying goes. Iamwatch just concluded in Singapore. In many ways it was similar to Tempus: also staged by local retailer The Hour Glass, a watch fair of sizeable scale, but unlike the 2004 event, Iamwatch was largely focused on independent watchmakers. Most crucially, it was also casual – the prescribed attire was Hawaiian shirt – which allowed for more personal interactions with industry personalities. As one of the largest retailers in the world, The Hour Glass has the pull to round up watch enthusiasts, and a great number turned up for Iamwatch, ranging from mega-collectors to royalty. Naturally, the watches spotted were diverse and often incredible. Many multi-million-dollar watches were circulating within the event, including famous examples that sold for record prices at auction, including the Patek Philippe ref. 2523 world time with a blue enamel dial and “Gobbi” signature. And even the Patek Philippe Cubitus was spotted on several wrists, the day after its launch in Munich. But 20 years on after Tempus, the enjoyment, significance, and enduring memories of an event like Iamwatch – for me personally – is no longer the watches, but the people. It was the moments, often during downtime or after the doors closed, when I got to converse with watchmakers ...
