Learn more about Timex
The Waterbury Clock Company was founded in Connecticut in 1854, part of the brass industry that made the region the centre of American clockmaking. Its descendants became Timex, and the company's history is one of making timekeeping cheap enough that everyone could have it.
The first breakthrough was the Yankee, a pocket watch sold from 1896 for one dollar — roughly a day's wage — which sold in the tens of millions and was marketed as the watch that made the dollar famous. Mark Twain and Theodore Roosevelt both carried one.
The company supplied enormous quantities of military timing equipment during both world wars, and its wartime work with Ingersoll and on fuse mechanisms shaped its post-war manufacturing.
The modern brand was defined by advertising. From 1956 Timex ran televised torture tests — watches strapped to outboard motors, dropped from cliffs, fired from crossbows — under the slogan it takes a licking and keeps on ticking. The watches used hardened Armalloy bearings instead of jewels, which made them cheap and, crucially, genuinely durable.
Indiglo, the electroluminescent dial lighting introduced in 1992, became the company's best-known technology after a Timex wearer used one to guide people down a stairwell during the 1993 World Trade Center bombing.
Timex remains privately held and produces the Weekender, Expedition, and archival Marlin lines.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Showering yes, swimming no. 50m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.
Water resistance explainedWill the glass scratch?
Yes, but it polishes out. Acrylic marks easily and a scratch can be buffed away at home, which is why vintage-style watches still use it.
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 40 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
What size strap does it take?
18mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Is it a men's or women's watch?
Listed as men's, though at 40mm it sits in the range that suits anyone.
