Zero West LS-1 Land Speed Chronograph

Created by British watch brand Zero West, the LS-1 Land Speed Chronograph is probable the only British made bullhead chronograph watch. This automatic chronograph watch model is a tribute to motor car racing.

The 1920’s saw great international competition in land-speed record attempts. A fierce international rivalry existed for holding the much coveted land-speed record. During the 1920’s the land-speed goal was to break the 200mph barrier and during that decade, the land-speed record was broken no fewer than eleven times.

The elusive 200mph barrier was finally broken on 29th March 1927 at Daytona Beach, USA, by an Englishman called Sir Henry Seagrave, driving a British built Sunbeam car called “Mystery” aka Sunbeam 1000 hp. The speed recorded was 203.79 mph.

It was an incredible car built by the British Sunbeam Motorcar Company of Wolverhampton. A colossus at 24ft long, 8ft wide and weighing in at 4 tons it was clad in aluminium alloy and painted in a bright red livery. Two 22.4 litre V12 Sunbeam Matabele aero engines, synchronised and mounted in tandem powered the car, one in front and one behind the driver cockpit. Transmission was via a 3 speed gearbox, its final stage being twin chain direct drive to the rear wheels.

The record was then broken in February of the following year by another Englishman, Sir Malcolm Campbell, at a speed of 206.956 mph.

Seagrave however went on to retain the record again in 1929 in a car called Golden Arrow at a speed of 231.446 mph, and once again Britain’s dominance in leading the world in engineering and setting new land speed records was upheld.

Zero West celebrates this British engineering achievement with their new LS-1 Land speed bullhead chronograph. This watch is powered by the legendary Valjoux 7750 Swiss automatic movement. Presented in a “Bulls Head” configuration, LS-1 harks back to the dashboard mounted timing watches seen on speed record and racing cars of the 1920s.

The main body is machined from billet 316L stainless steel and finished in matt black PVD with straight barrel knurl and brushed top chamfer. The backplate and lugs are billet machined from a single piece of 316L stainless steel which is then mirror polished to create a beautifully sculpted cradle for the body to nest into. Time adjustment is by an oversize diamond knurled and dome topped crown and the chrono function pushers are sculpted into the cradle to accentuate the flowing three-dimensional form of LS-1.

The dial has a contemporary feel with balanced vintage design. A satin steel index ring frames the ink black dial, which features white numerals in SuperLuminova X1 pigment along with the matt steel hour and minute hand.

LS-1 is fitted with a leather strap which is hand crafted in the Zero West workshop using Horween leather, which is known for its beautifully supple and highly water resistant qualities. The result is a rugged, vintage feeling strap that will develop a lovely patina over time.
