Stepping up in Zenith's range
The 41mm grade titanium case combines brushed and polished surfaces, saving around 30% in weight compared to stainless steel. A vertically brushed fixed bezel carries an engraved 1/10th-of-a-second scale, which works in step with the central chronograph hand — that hand completes one full revolution every ten seconds. The nickel-grey sunburst dial carries rhodium-plated baton hour markers and three overlapping sub-dials in graduated shades of grey: a 60-second counter at 3, a 60-minute counter at 6, and running seconds at 9. The date sits at 4:30. Inside, the El Primero 3600 runs at 36,000 vph with a 60-hour power reserve and a star-shaped oscillating weight. An integrated three-link titanium bracelet with a folding clasp completes the watch, and sapphire crystal with anti-reflective treatment covers the dial.

Learn more about Zenith
Georges Favre-Jacot founded Zenith in Le Locle in 1865, aged twenty-two, with an idea that was radical for the Swiss industry: bring every trade needed to make a watch — movement, case, dial, hands — under one roof and one management. The integrated manufacture was largely his invention, and the Le Locle site he built is still in use.
The approach produced results at observatory trials, where Zenith accumulated more precision awards than any other manufacture. The name itself came from a calibre Favre-Jacot considered the summit of his work.
Its defining achievement is the El Primero of 1969, developed over seven years and announced in the same year as the Heuer-Breitling consortium's Calibre 11 and Seiko's 6139. It was an integrated automatic chronograph beating at 36,000 vibrations per hour, allowing measurement to a tenth of a second — a frequency almost nothing else matched for decades.
It nearly did not survive. When American owners ordered the mechanical tooling scrapped during the quartz crisis, a watchmaker named Charles Vermot hid the plans, presses, and cams in a walled-off attic. When demand for mechanical chronographs returned, Zenith could restart production because of him. Rolex used the El Primero in the Daytona from 1988 to 2000.
LVMH acquired Zenith in 1999.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 100m it is rated for swimming and snorkelling, though not for diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
Quartz, automatic and solar comparedHow long does it run for when it's not worn?
About 60 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
Is it a men's or women's watch?
Listed as men's.
Cheapest place to buy
Both Goldsmiths and Mappin & Webb list it at £11,100, so choose on delivery and warranty rather than price.
