Chapters

  1. 1985 to 1994

    Every function through the crown

    The Aerospace of 1985 combined analog hands with two LCD screens in a titanium case, and every function, from the 1/100 second chronograph to the alarm, ran from the crown. The first reference, 80360, measured 40 mm and still read Navitimer on the dial. In 1994 ref. 56062, known as the Aerospace II, enlarged the lower screen.

  2. 1995 to 2000

    A watch that calls rescuers

    In 1995 Breitling announced the Emergency, a 43 mm titanium watch with a transmitter on the 121.5 MHz air distress frequency, developed with Dassault Electronique. Development took nearly a decade and $7 million, and the watch could not be sold until Swiss regulators approved it in May 1996. US approval came in 2000.

  3. 2001 to 2012

    Rescues on the record

    The Aerospace moved to the SuperQuartz caliber 75 chronometer in 2001, then grew to 42 mm with a backlit caliber 79 as the Aerospace Avantage in 2005. Meanwhile Emergency owners kept activating their beacons: two British pilots after a helicopter crash near Antarctica in 2003, a stranded hunter in Alaska in 2012.

  4. 2013 to 2019

    Two frequencies, one wrist

    After Cospas-Sarsat stopped satellite monitoring of 121.5 MHz in 2009, Breitling spent five years on the Emergency II, shown at Baselworld 2013. It added the 406 MHz satellite frequency and a rechargeable battery, in a 51 mm titanium case. The same year the Aerospace Evo took the case to 43 mm.

Worn by

Bertrand PiccardExploration1999

Wore a Breitling Emergency during the Breitling Orbiter 3 flight, the first nonstop round-the-world balloon flight, from 1 to 20 March 1999. The beacon was his fallback if the balloon came down.

Brian JonesExploration1999

Piccard's co-pilot on Breitling Orbiter 3 also wore an Emergency, an orange-dialed one according to Fratello.

Quentin SmithExploration2003

The British helicopter pilot ditched in the Drake Passage in January 2003 during a pole-to-pole attempt and deployed his Emergency's antenna; a rescue plane located the crew nine and a half hours later.

Colin PrescotExploration2000

The British balloonist told The Independent he was given a blue Emergency by Breitling after his round-the-world balloon attempt and wore it as a last-resort safety device.

Andy ElsonExploration2000

Prescot's ballooning partner, who according to Prescot wore his orange Emergency all the time.

Jan FrodenoSport2024

The three-time IRONMAN world champion rode the TORTOUR 500 ultracycling race in July 2024 wearing the Endurance Pro, according to Breitling.

Moments

2012. Alaskan hunter Mark Spencer, hypothermic after more than 48 hours alone, was found by helicopter after activating his Emergency; his separate beacon put him four miles off.

2003. Quentin Smith and Steve Brooks were found in a raft in the Drake Passage after activating an Emergency on 121.5 MHz; Smith said no one had survived a ditching there before.

1999. Breitling Orbiter 3 completed the first nonstop balloon flight around the world on 20 March 1999, its two pilots wearing Emergency watches. The capsule went to the Smithsonian's National Air and Space Museum in 2000.

1997. An Emergency saved the 13 crew of the Mata-Rangi, a reed boat blown off course by a storm after sailing from Easter Island toward Australia.

1995. In December 1995 the Emergency proved itself in a Hong Kong search-and-rescue exercise involving the RAF, the Royal Navy, the US Air Force, Navy and Coast Guard.

FAQ

What lug width does the Breitling Professional use?

Breitling Professional references use 18 mm or 22 mm or 24 mm depending on the reference and case size, so check yours in the list below. The most common is 22 mm (61 of 80 references with a known width). The Breitling Professional ref. E79363101B1E1, E79363101C1E1 and 59 more take 22 mm (listed by the maker). The Breitling Professional ref. M78367101B1W1, EB5010221B1E1 and 8 more take 24 mm (listed by the maker).

Do all Breitling Professional references take the same strap?

No. 5 different lug widths appear across the line, often by case size or generation. Check the reference engraved on the case back or between the lugs.

What is the lug width of the Breitling Endurance Pro 44?

22 mm. Breitling's current straps for it taper to an 18 mm or 20 mm buckle depending on the reference (22/18 mm on the standard models, 22/20 mm on some IRONMAN editions).

What strap size does the Endurance Pro 38 take?

18 mm between the lugs, with an 18/16 mm rubber strap and a 16 mm Breitlight tang buckle.

Can I change the strap on an Endurance Pro?

Yes. Breitling says the rubber strap can be replaced with other compatible Breitling straps, and at launch it sold matching Outerknown ECONYL NATO straps separately.

What lug width does the Aerospace use?

Current 43 mm Aerospace references list 22 mm between the lugs, with a strap or bracelet tapering 22/20 mm.

Why is the Chronospace Military strap so wide?

Its 46 mm case has 24 mm between the lugs; the polyamide strap tapers from 24 to 20 mm at the buckle.

Help

What is lug width?

The gap between the two lugs that hold the strap, in millimetres. A new strap must match it exactly: 20 mm lugs take a 20 mm strap.

Measure it in 30 seconds

  1. Take the strap off, or look at the back of it: many straps print their width.
  2. Measure the inside gap between the lugs with a caliper or a millimetre ruler.
  3. Round to the nearest whole millimetre. Most watches use 18, 20 or 22 mm.

Strap, quick release or system?

Most watches use spring bars, so any strap of the right width fits. Many smartwatches use their own band system instead, such as Apple Watch bands or Garmin QuickFit.
