The Omega Flightmaster is a legendary chronograph watch introduced by the Swiss watchmaker Omega in 1969. It was specifically designed for professional pilots, and its design reflects this intended use.

Key Features of the Omega Flightmaster:

  2. Dial: The dial is complex, featuring three sub-dials that allow easy tracking of various functions. It also includes a GMT indicator, enabling the wearer to monitor time in a second time zone.

  3. Functionality: The Omega Flightmaster is equipped with chronograph functions, a tachymeter, and GMT (dual time zone) capabilities. These features make it ideal for aviators who need precise timekeeping during flights.

  4. Movement: The watch is powered by the Omega Calibre 910 movement (later versions used the Calibre 911), known for its accuracy and reliability.

  5. Durability: Like all Omega watches, the Flightmaster is known for its durability and reliability, making it a popular choice among professional pilots and collectors alike.

STRAP

LEATHER STRAP FOR AN OMEGA FLIGHTMASTER WATCH FROM THE 1970S.

The owner of a rare Omega Flightmaster watch from the 1970s (https://monochrome-watches.com/in-depth-the-omega-flightmaster-the-special-one/) approached me with a special order. These watches, produced in limited quantities and intended for professional aviators, are true masterpieces of watchmaking. Previously, the watch came with an original metal bracelet, but time spares even the best materials.

The customer noted that metal bracelets, despite their initial appeal and durability, are often uncomfortable. They are not always balanced in weight with the watch case, making them less comfortable to wear. In cold weather, the metal cools the wrist, causing discomfort. Additionally, such bracelets can pull hairs on the wrist and deform over time, especially with vintage models.

Understanding all these issues, the client decided to replace the metal bracelet with a custom-made leather strap. We discussed the details for a long time and finally decided on a classic rally design from the 1960s. This style features stylish perforations, which provide additional wrist ventilation and are reminiscent of the shapes of the watch’s extra dials.

For the strap, we chose Alran “Sully” goat leather from France. We selected a dark blue color for the strap, which harmoniously matches the color of the watch’s additional hand and symbolizes the endless sky. The white stitching on the strap adds elegance and echoes the white markings on the dial, creating a unified and stylish look.

The strap measures 22 mm in width at the attachment and 20 mm at the buckle, with a length of 115 mm and 75 mm. The strap’s lining is made from hypoallergenic, waterproof leather, ensuring comfort and durability. Additionally, the strap is equipped with a folding clasp for convenience and secure fastening.

HISTORY

https://en.wikipedia.org/wiki/Omega_SA

OMEGA is the last letter of the Greek alphabet and symbolises accomplishment and perfection - qualities that have been inherent in every OMEGA watch since the company's founding by Louis Brandt in La Chaux-de-Fonds, Switzerland, in 1848.

The brand's reputation for innovation and quality has led to numerous awards over the company's 150-year history, starting as early as 1900 with the Grand Prix at the Paris World Fair and continuing with the world precision record of 97.8 points at the Kew-Teddington observatory in England in 1936.

OMEGA went on to be official timekeeper at no less than 21 Olympic Games, bringing numerous innovations to Olympic sports over the years, such as the first electronic timekeeping at the Helsinki games in 1952 - the same year in which the company was awarded the Olympic Cross of Merit for its outstanding contribution to sport.

On account of its precision and reliability, OMEGA's Speedmaster watch was chosen by NASA as its official chronometer in 1965 and 4 years later was the first watch to be worn on the moon, when, on 21 July 1969, Neil Armstrong made his giant leap for mankind.

In more recent years, OMEGA has continued to build on its reputation for precision and innovation, presenting the world's first self-winding wristwatch with central tourbillon (launched in 1994) and the revolutionary coaxial escapement sur developed in conjunction with renowned English master watchmaker George Daniels first offered in limited series in 1999.

OMEGA owes a large part of its watchmaking excellence to the quality of its movements. These magnificent watches are highly collectible, and hold a very special place in many collectors showcases.

There seems to be an aura about Omega watches that captivate this collector especially.

RECOMMENDATIONS

All Antique watches are mechanical. Many repairs will not be cheap, as most likely they will require replacement of non-standard parts (unlike most late model watches).

  • Antique watches should not be beaten or dropped - because repairs may be expensive.
  • Antique watches are generally NOT waterproof. This is because waterproofing was not in general production until the middle of the 20th century for most watches. Therefore you should protect your antique watch from exposure to moisture.
  • If your watch becomes wet it should be dried off quickly. Carefully open all covers and use a hair drier to blow dry the movement, dial, covers, crown. This will reduce the amount of rust.
  • If your watch becomes wet with any kind of salt water you should immediately immerse or spray your watch with fresh (no-salt) water to remove all the salt from the works before drying the watch completely. Any salt left in the watch will combine with moisture in the air to rust metal components of the movement, case etc.
  • Winding any mechanical watch tight may break the mainspring. If you can avoid it do not wind the watch hard.
  • When adjusting the hands of your watch, move them in a clockwise direction only. Counter-clockwise adjustments may damage the movement. It is desirable to adjust the hands of your watch at the same time every day. An automatic or self-winding watch should be worn for at least 8 hours a day. It is a mechanical watch in which the mainspring is wound automatically as a result of natural motion of the wearer's arm, to provide energy to run the watch, making manual winding unnecessary.
  • If you must adjust counter-clockwise make it for small adjustments only (i.e. for minutes, NOT hours).
  • Be careful and gentle when adjusting the movement speed (faster or slower). Don't make sharp movements, and don't touch other components in the movement especially the pendulum mechanism.
  • Every 2-3 years it is necessary to service and oil vintage watches. If the course of your watches is worsening and the accuracy of the reduction in the duration of the clock (autonomy) from one fully wound spring - it need a service.
  • IF the watch is dirty - allow the watch to run down, don't wind it again until you have it serviced by a qualified watch repair expert. Dust will absorb and remove important lubricants and cause the movement pieces to wear down.
  • To clean the case, dial and crystal you should use a cloth that does NOT leave fibers as these may get caught up in the movement. Check with your Watch repair expert to get an appropriate cloth.
  • Keep your antiques watch away from magnets. Strong magnetic fields may affect the accuracy of your watch since some vintage watches were made with iron based components in the movement.
  • Most Cases and Covers are fine components and will not handle abuse well. The watch should not be shaken, beaten, or stressed.
  • Antique watches generally experience an error of up to 5-7 minutes a day. Any accuracy of +- 5 minutes is very good.
  • Mechanical watch is not recommended to use for engage in extreme sports, and expose them to excessive vibration loads. Recoil force, which take on the clock, affect their reliability and precision. No matter how perfect was not anti-shock mechanism, there is always the chance of excessive load that details of the mechanism can not survive.
  • Watch with calendar. It is not recommended to adjust, the date between 20.00 and 06.00, because at this time involved a mechanism for automatic adjustment date. Translation pointers calendars manually in this position arrows may damage the mechanism. Date changes should be made, relegating pre-clockwise to lower sector of the dial (for example, to position 6 (18.00) hours).
  • Chronograph watches. In most cases, these watches contain the "start/stop" button and "reset" button. It is strongly recommended not to press the "reset" if the chronograph is running. Before you use the "Reset" button need to stop the chronograph by button "start/stop". Using the "reset" when running chronograph can damage the mechanism of most models of watches.
