Collection: Jack Mason Pursuit Pro

The Pursuit Pro is the most purpose-built watch Jack Mason makes. It is the only anti-magnetic model in the range, which matters more than it sounds: magnetism is the most common cause of a mechanical watch suddenly running fast, and it is picked up from ordinary things like speaker magnets, laptop cases, and tool bags.

Inside is the Swiss La Joux-Perret G101, an automatic with a 68-hour power reserve — enough to sit through a full weekend off the wrist and still be running Monday morning. The case is 42 x 47mm 316L stainless steel with a 7.5mm crown, a rotating bezel, a hardness coating for scratch resistance, and a sapphire crystal, water resistant to 200 meters. It comes on a nylon strap with a hook-and-loop closure, which dries fast and adjusts without tools.

King Jewelers carries it in Shadow, a black dial on a black strap, and Hunter, a green dial on a tan strap.

The most purpose-built watch Jack Mason makes

The Pursuit Pro is the outdoor watch in the Jack Mason range, and the only anti-magnetic model the brand offers. Where the Strat-o-timer is built for travel and the Canton for daily wear, the Pursuit Pro is built for conditions — long days away from a winder, equipment that generates magnetic fields, and water.

Anti-magnetism, and why it is the right feature here

Magnetism is the most common reason a mechanical watch suddenly starts gaining time, and it comes from ordinary sources: speaker magnets, laptop and tablet cases, magnetic tool holders, headphones. A magnetized hairspring can put a watch minutes out per day until it is demagnetized. Building magnetic resistance into a watch meant for tool bags and truck consoles is a practical decision rather than a specification-sheet one.

A Swiss movement with a weekend-proof reserve

The Pursuit Pro runs the Swiss La Joux-Perret G101 with a 68-hour power reserve — substantially longer than the 42 hours typical of the category, and enough that a watch set down on Friday evening is still running on Monday morning.

Built in the United States

Designed in Dallas and assembled in the United States by Jack Mason's own watchmakers, with each movement hand-regulated before it ships.
