Burgess Clock B is the World’s Most Precise Pendulum Clock and is Made to a 250-Year-Old Design by John Harrison, Longitude Prize Winner and Inventor of the Marine Chronometer

Two-hundred fifty years ago, Longitude Prize-winning clockmaker John Harrison made clocks losing just one second per month. But that wasn't enough for him: in his later life, Harrison claimed that he could make a wall clock with a then-unheard-of-precision of just one second over 100 days! And 250 years later, it turns out he was right.

The Greatest Horological Masterpieces of All Time: the Harrison H4 – A Groundbreaking Timepiece That Solved The Longitude Problem

A series of features identifying the most extraordinary mechanical masterpieces in history, blending precision, innovation, and craftsmanship. We all have our favourite timepieces either in our collection or those incredible horological masterpieces that have been invented or created through the ages. This series will showcase examples from the previous centuries up to the present day and look at the importance and impact on modern day timekeeping.  John Harrison’s H4 Chronometer was a groundbreaking timepiece that solved the longitude problem, a major challenge for navigation during the 18th century. Before Harrison’s work, sailors had no reliable way to determine their precise east-west position at sea, leading to deadly navigation errors. The British government, through the Longitude Act of 1714, offered a large prize to anyone who could develop a practical solution. Sir Cloudesley Shovell, by Michael Dahl, about 1702-5 (L); The Association with the Eagle, Rumney and the Firebrand, Lost on the Rocks of Scilly, October 22, 1707 (R). Image courtesy of the © National Maritime Museum, Greenwich, London The Catalyst for the Longitude Act In the early 18th century, determining longitude at sea was one of the greatest challenges in navigation. While sailors could measure latitude using the position of the sun or stars, longitude required precise timekeeping-something that was nearly impossible with the unreliable clocks of the time. The inability to determ...

Hands-On: Ulysse Nardin Marine Torpilleur 42 mm

One of the longest-lived models in the Ulysse Nardin line up, the Marine is modelled on vintage marine chronometers, the precision clocks in gimballed boxes found on ships of old. Originally introduced in 1996 as the Marine Chronometer 1846, the watch was one of the brand’s signature models during the tenure of former owner Rolf Schnyder, a larger than life entrepreneur who made Ulysse Nardin (UN) a presence in contemporary watchmaking. Several generations later, the design is now found on an entry-level model that is surprisingly accomplished despite being quite affordable, the Marine Torpilleur 42 mm. (NB: The version pictured here is in rose gold and naturally costs more; the steel model is priced under US$7,000.) Initial thoughts The Marine Torpilleur is an interesting proposition because it’s a fairly thin sports, or at least sporty, watch that has an obviously classical design that still manages to be functional. It manages that because the design is based the marine chronometer, a classical yet functional instrument. And the Marine Torpilleur is powered by the excellent, in-house UN-118 movement, while being priced at a little under US$7,000 in steel. That sets it apart from most watches in the same price segment, because the Marine Torpilleur has a competent dial and case, but an excellent movement. So from a technical perspective, it is a strong value-buy. The watch is largish but slim, with a dial that’s essentially a replica of a marine chronometer di...

Up Close: Breguet Marine 5517 in Titanium

Breguet today is highly regarded for its watches that classically designed but often powered by innovative, high-tech movements, like the Classique Chronométrie 7727 with magnetic balance pivots, or the recent, elaborately finished skeleton tourbillon 5395. The brand is not, however, known for its luxury-sports watches (its line of Type XX aviator’s chronographs are entry-level and not quite sports watches). But last year Breguet unveiled the latest – and best – version of its luxury-sports watch, the Marine 5517. An under-appreciated contender in the category, the new Marine more conservative in style than its competition, but built to an admirably high standard. The Marine 5517 in titanium with a matching bracelet Horloger de la Marine Unlike its competitors, Breguet was relatively late to the luxury-sports watch segment (though not as late as A. Lange & Söhne, which launched the Odysseus last year); the original Marine only made its debut in 1990. The model name was inspired by Breguet’s appointment in 1815 as Horloger de la Marine – clockmaker to the French navy, an appointment it held for over 150 years. Designed by Jorg Hysek, perhaps the most famous watch designers of the 1990s, the first-generation Marine was distinguished by its fluted, domed crown, but otherwise looked pretty much like any other Breguet. That was replaced in 2005 by the second generation, a major redesign that gave it a more distinctive style. The practical robustness of the Marine...

New and reviewed: TAG Heuer Monza Flyback Chronometer

We take a quick look at one of the first novelties in 2023: the stunning and uber-cool TAG Heuer Monza Flyback Chronometer.

Hands-On: TAG Heuer Monza Flyback Chronometer

LVMH Watch Week, the year’s first significant watch fair, just kicked off in Singapore. In some ways a warmup for Watches & Wonders in March – the biggest watch fair of the year – the LVMH Watch Week is where the watchmakers owned by the French group show off their wares. Amongst them is TAG Heuer, which has revived one of its less-known racing chronographs from the 1970s but in a thoroughly modern style. The Monza Flyback Chronometer is a flyback chronograph featuring an open-worked dial and a 42 mm carbon composite case. Initial thoughts Perhaps the most aggressively modern chronograph in TAG Heuer’s current line-up, the new Monza liberally reinterprets the 1970s original. While the vintage Monza is not famous as the Carrera or Monaco, it is interesting in several respects, including the fact that it was the first serially-produced Heuer to sport a black-coated case. The carbon case and open-worked, asymmetrical dial show another face of TAG Heuer, but one that still fits with its motorsports-chronograph heritage. Certainly a TAG Heuer that is different, the Monza has clearly been conceived to cater to contemporary tastes, which is a good thing given that TAG Heuer already has an ample offering of faithful vintage remakes. But the new Monza comes with a caveat, a steep price. Coming in at US$13,500, the Monza costs double the Autavia Flyback Chronograph that has the same movement but a no-frills steel case. Even considering the carbon composite case and fanc...
