Flight Engineer

Watches for science and industry - that was already our expertise in the 60s of the last century and continues to be so to this day. Since the founding of our company, we have been making watches that are worn with an occupational relation in challenging situations. Pilots, scientists, researchers and technicians rely on Guinand instrument watches in everyday life and in extreme situations. With our model Flight Engineer we write a new chapter of our instrumental watches.

Flight Engineer Ferritgrau

Our latest version of the Flight Engineer has a ferrite gray dial with large, easy-to-read digits. Dial indices and numbers are covered with white luminous material of the highest luminosity Grade X1.

Optionally, we produce the magnetic field protected Flight Engineer Ferritgrau with a satin or glass bead blasted housing.

The Flight Engineer

The Flight Engineer, formerly an indispensable crew member of all large aircraft, has the task of monitoring and operating the aircraft systems such as the pressurized cabin, the fuel supply and the engines. In case of error, it provides remedy.

The Flight Engineer is thus to a certain extent the technician on board the aircraft and responsible for the largely highly complex on-board systems - relying on a highly reliable wrist watch protected against magnetic influences.

The Watch

Reduced to the essentials, the time display via 3 hands, the readability of the watch is perfect. The date indication is positioned on a position of the dial which does not disturb the large hour number.

Another special feature of this instrument watch, however, is conceiled in the case. A soft iron inner housing consisting of 3 housing parts effectively shields the inserted automatic movement against magnetic fields. Up to a magnetic field strength of 1000 Oerstedt this cage protects against magnetic fields by passing the magnetic field around the movement and prevents permanent magnetization of the balance spring and other steel watch parts (levers, screws, shafts).

The Dial

Slightly shiny black or ferrite gray dial, numbers and Indexes coated with white luminous color of superior Grade X1 quality, Minute- and hours hands and arrow of the second hand filled with white luminous color.

The Movement

For the Flight Engineer, we using a movement of the Swiss family owned company Sellita, based in La Chaux-de-Fonds. The SW220-1 is produced since 2004 and considered as well-engineered, the basic construction dates from the year 1982. Sellita, manufacturer of watch movements, supplies Guinand with the movement for this watch in a decorated version with Perlage, Geneva stripes, blued screws and Glucydur balance.

At Guinand each of these movements is regulated once again in 5 positions before the final control of the watch ends with an accuracy test of several days.

The Housing

Case made of stainless steel, satinized, pilot bezel made of light-weight alloy, rotatable in two directions, orange luminous capsule on the zero marker. Inner housing made of special material for magnetic field shielding.

The Strap

Solid Strap Flight Engineer

For the Flight Engineer we manufacture the solid strap Type H in a overall satinized variant

Magnetic Field Protection

Magnetic fields surround us in everyday life - be it in our daily work, in our spare time or while traveling. Whereas in the past scientists and technicians were mainly affected by the influence of strong magnetic fields on their measuring instruments and watches, the development of magnetic materials has led to extremely strong and very compact permanent magnets which surround us in everyday life in many places.

These magnets certainly generate magnetic fields of a strength of 1000 Oe / 1000 Gauss in the distance of a few centimeters around the magnetic axis. The functionality and precision of a mechanical wrist watch can already be affected by a magnetic field of 60 Oe / 60 Gauss.

The standard DIN 8309 or its international counterpart ISO / DIS 764, which is considered to be non-magnetic watches, defines that such a watch will continue to operate when subjected to a magnetic field of 4,800 A / m (60 Oe) and then deviate by a maximum of 30 seconds / day.

For this purpose, components made of Glucydur or Nivarox, which are less susceptible to magnetic fields, are used in the movement. If stronger protection against magnetic fields is required, a combination of two measures has proven effective. The use of magnetically insensitive watch parts and additionally a protective shield made of soft iron.

For the Flight Engineer, we use a very solid inner casing made of nickel-plated soft iron. In order to avoid the penetration of magnetic fields through housing openings as far as possible, the inner housing is not just a simple turned part but a complex shaped turning and milled part with only a small hole for the stem and a minimized hole for the date display. We use e.g. for the dial soft iron with the material number RFe 60 / 1.1015 according to DIN 17405. The proportion of pure iron (Fe) is in such materials well over 99%.

_{Oersted (unit symbol Oe, after the Danish physicist Hans Christian Ørsted) is the unit of magnetic field strength in the Gaussian and CGS electromagnetic system of units.}
