Serviced Vintage 1970's Hamilton Chrono-Matic Pan Europ 703 Cal 11 Watch Box. The history of the Calibre 11.
Starts at the end of 1965. As Büren had pioneered the production of micro-rotor movements, Gérald Dubois of Dépraz & Co.
A chronograph specialist figured out that these would be thin enough to be the base for a modular chronograph movement. Dubois contacts Hans Kocher of Büren Watch Co. In need of commercial partners, they manage to convince first Jack Heuer and then Willy Breitling to support the project.On February 2nd, 1966, an agreement is signed. The four-party Chronomatic consortium is born, including two rival brands teaming up to develop their own automatic chronograph. For confidentiality purposes, the development is code-named Project 99. The convention signed on February 2, 1966, between Dépraz & Co.
Heuer-Léonidas SA and Léon Breitling SA. The partners asked Büren Watch Co. To build the blanks and the automatic movement of an automatic chronograph, the basic execution of which is designated by calibre No.They have an exclusive right to use this calibre. They plan to have Dépraz develop and manufacture the chronograph mechanism to equip this calibre. Büren is in charge of the base calibre. Dépraz of the chronograph mechanism. Three brands Heuer, Breitling and Hamilton (who acquired Buren during the development process) will fit the movement inside their watches.
A patent application for the Calibre 11 is filed in September 1967. At the end of 1968, about 100 pre-production movements are assembled in prevision of the 1969 Basel fair. On March 3rd 1969, the movement is officially presented, simultaneously in New York and Geneva.
A month later, the three brands present their first chronographs at the 1969 Basel fair. With the practicality and comfort of automatic winding, the chronograph becomes a staple of motorsport the Calibre 11 is used to power iconic watches by Heuer (Carrera, Monaco, Autavia), Breitling (Chrono-Matic) and Hamilton (Fontainebleau).And later by other brands such as Bulova, Kelek, Zodiac, Elgin, Stowa. So, who won the race? Zeniths automatic chronograph was the first to be unveiled to the world. It was presented during a press conference in January 1969 and christened El Primero (the first in Spanish). The reality is a bit more complex. There are endless debates about which was the first automatic chronograph, as both the Seiko and the Chronomatic movements were announced later the same year.
Whats more, El Primero was not the first to hit the market. But the controversy about who came first doesnt really matter anymore what is important is the impact that these movements had on watchmaking history. Since then, the automatic chronograph has remained one of the most popular complications. The Calibre 11 is a 17-jewel modular chronograph measuring 31mm x 7.7mm. This modular architecture implies first a base movement, a micro-rotor automatic calibre made by Büren, in charge of the timekeeping part.Beating at 19,800 vibrations per hour, it boasted 42 hours of power reserve. Manufactured by Dépraz, the lever chronograph module is assembled on the backside of the base movement. This movement has a bi-compax display, with a 30-minute counter at 3 oclock and a 12-hour counter at 9 oclock no running seconds sub-dial.
The date is indicated at 6 oclock. The unusual crown position, at 9 oclock at the opposite of the chronograph pushers, is a signature feature of the movement.
THE CALIBRE 11 AND ITS EVOLUTIONS. Like most movements, the Calibre 11 has been optimized several times over its lifetime. As early as 1969, a barrel spring providing less torque is used. The date jump mechanism is adapted. The sliding pinion is changed and made in steel.In 1971, a variant running at 21,600 vibrations per hour and named Calibre 12 is introduced. It becomes the main product of the calibre family. It uses a stronger barrel spring. The gear train and balance wheel are adapted. The chronograph hammer is modified to improve shock-resistance.

The watch should not be used in the water! All diving watches, even recent, should be sent for a qualified water sealing service each year prior to diving season. Any props display that might appear in the pictures is not included in the sale. We do check them out to make sure they are keeping time and running, however we do not service each and every watch and it is possible that servicing may be necessary at your expense. Servicing a vintage watch is highly recommended given that we dont have service record in most cases.Please see our service level guild for more information. Please bear in mind the age of these watches, in some cases 50-80 plus years old and due to the age of these watches we do not guarantee for water tightness whatsoever, even if it is marked waterproof on any watch we sell. Remember that seeing the item at very high magnification, as in the pictures that I provide, brings to life small defects that the human eye does not perceive. That is why many people will like even more the watch after seeing it for real. Please don't send me a message telling me what you think is the value of the item, or asking me if I will consider an offer in the amount of x or what is my best price.
This is the most effective way to avoid the disappointment of seeing the item go to someone else. I do not guarantee time keeping on any of my vintage watches, even if the time keeping is perfect. Very old watches keep good time but do not expect the accuracy of a modern watch.
Vintage watches are very delicate and I package to the highest degree to prevent damage. High altitude flights can be hard on watches due to extreme temperature changes. This can cause the oil viscosity to decrease (gum up) and prevent a watch from ticking the balance moving freely etc. It may need to be oiled when it arrives regardless of its recent servicing (if applicable). Although this is only a very slight possibility it can occasionally happen.
Unfortunately lot of sellers are calming the watch has been serviced where the watch has not been. So please be careful and ask questions from sellers first.As far as my watches please see below. Watches I sell can have the following service Levels.
Level # 1 Experts Watches Serviced. Serviced by our service repair center with over 40 years of experience very old school and very hard to find these day. Our routine service includes the following. Complete disassembly of the watch. Completely disassembled, cleaned, oiled, and timed using state of the art equipment.Clean all moving parts with specialized cleaning solvents. Proper lubrication with only the highest-grade lubricants and oils during the reassembly process.

(Overhaul Lubricants, Gaskets, Sealing, Regulation, MISC testing). The was inside case is marked and dated by the service man.
Receipts are available on request. Level #2 Serviced by previous owner. This watches are inspected and timed to make sure it meets the vintage watch timing standards.
Level #3 Inspected and timed. Are less expensive watches or newer watches that does not need it might not go through his process.
Actually, wearing the watch in the pulse will get you different results for sure, because the watch will. Be subject to very different positions and temperatures. Like a car, a mechanical watch will require periodic maintenance by an expert watchmaker. Recommendations for the owner of antiquarian watches. 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. If you must adjust counter-clockwise make it for small adjustments only i. 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 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. Welcome to EXPERTS WATCHES EXPERTS WATCHES was born from a passion of collecting wristwatches for over 40 years. This passion has evolved into an opportunity to create the best destination for luxury & vintage pre-owned timepieces.
