(Sometimes incorrectly referred to as the Master Control Geographic, the correct name according to the instruction book and the manufacturer’s catalog is Master Geographic.) A different model is called Master Compressor Geographic.

This model is 18K White Gold, movement is Calibre 929/3, 38 jewels, sapphire crystal. Weighs about 3.5 ounces with band.



Back of the case has the Master Control badge on a Hunter style cover that opens to reveal the works. Movement is stamped 929/3 and number 5060095.

Main face displays hour, minute, and second hands. This model also has
a date face with “31” in red as a reminder to bump the date forward in shorter months;
and a Reserve de Marche (Power Reserve) indicator with a single hand, calibrated from below 10 hours to the maximum reserve of 40 hours.

Also has a second time zone dial with hour and minute hands. The second zone minute hand is always coordinated with the main dial minute hand and is not independently adjustable. The second zone hour hand is moved with the city displayed in the wide window at 6 o’clock or is adjusted by the crown winder at 3 o’clock. Near the second zone dial is a small day/night indicator.

The second hand on this automatic has nearly a sweep motion with only a barely perceptible jog or hesitation as it goes around. The hand does not stop and go as on a manual watch.

The Manufacturer’s Book of Time Pieces (Edition 2004/2005), page 64 shows an 18K White Gold (142.34.70) “Master Geographic” with a dark grey face. The model discussed here has a light silver color face with silver color hour and minute hands.

Under some light conditions the main hands can seem to disappear because they are similar in color to the face. A slight twist of the wrist brings them back to view since each hand has an angled “fold” down the middle with two parts of the top surface at different angles. With a slight wrist twist, one half of each hand becomes dark grey or black in appearance and easier to see.

The 3 o’clock crown winds the watch in the full-in position. About 15 forward winds will add 10 hours of reserve.

In the full or 2nd pull-out position, this crown moves the main time hands with a hacking second hand allowing this hand to stop while adjusting for more accurate setting. Instructions are to turn the crown clockwise when in the 2nd pull-out position.

In the first pull-out position this crown moves the second zone hour hand.

A 2nd crown (10 o’clock) turns the second zone city dial in the wide window in the 6 o’clock position. This crown can be turned in either direction. As this crown is turned, the city names pass in the window and the second zone hour hand moves.

Caveat: the watch has no provision for setting the second zone for fractions of an hour differences from world times.

To ensure correct time for an unfamiliar city, start with the local city in the lower wide window, then use the 3 o’clock crown to set the second zone to the local time. When any other city is shown in the window, the correct time for that city will show on the second zone face.

The date hand is incremented one day by use of the supplied tool pressed into the Corrector dimple at 2 o’clock. Caution: do not use this feature between 8 p.m. and 3 a.m. when the date change mechanism may be engaged.

Accuracy standard is -1 to +6 seconds a day. This watch loses about ½ second per day.

The same model is also available in Stainless Steel and 18 K Pink Gold.

Watch was fitted with a brown crocodile strap with 18K White Gold deployment buckle. Purchased in New York City September 2004.

For adjustable Winders, recommended setting is 800 Turns Per Day (TPD) in both directions
