Omega Speedmaster - A TIME CAPSULE WORLD MOOK MONO Special Edition Edited & Written by Kesaharu Imai Published by WORLD PHOTO PRESS A TIME CAPSULE—Omega Speedr~raster Front Cover: A TIME CAPSULE—Omega Speedmaster The story of the first watch in outer space. Edited & written by Kesaharu Imai. P2 As we make the transition into the twenty-first century, the Omega Speedmaster, small enough to fit in the palm of the hand, is in itself a time capsule of the twentieth century. P3 Foreword, The setting sun on a late autumn afternoon set scene for a visit from Mr Imai when he came to my office at the Van Nuys airport located in a suburb of Los Angeles. The creaking of the ffont stair5, as he entered the building, was reminicient of the erie awakening cry of a space craft preparing for laumch. I began my first Space Flight aboard Mercury-Atlas 9 thirty-three years ago! In looking back to those days, Mr Imai and I talked enthusiastically about the Omega Speedmaster, which served as a reliable personal tool throughout my mission duration completing 22 5 orbits around the earth! An impression of the universe was beyond my expectation and imagination. As a glimpse of limitdessness followed by an awe-inspiring view of the eatth are indeed indescribable. Being overwhelmed by an unprecedented experience I was not myself for some time till I noted the positive movement of ht e second hand on the Speedmaster, which in fact recorded such data as elapsed flight time and fuel consumption. "The development of science and technology today is undoubtedly the result of human wisdom which I believe stemmed from the passionate but romantic pursuit of scientists and engineers, said Me Imai. -

Floating Balance cont. Cleaning • Make sure the main spring has been let down before working on movement. • Use non-aqueous watch cleaner and/or rinse. • Agitate in cleaner/rinse by hand or briefly in ultrasonic. • Rinse twice and final in naphtha, Coleman fuel (or similar) or alcohol. • Allow to dry. (heat can be used with caution – ask me how I would do it.) Lubrication • There are two opinions. To lube or not to lube. • Place a vary small amount of watch oil on to the upper and lower jewel where the pivot wire passed through the jewel holes. -

This invention was chosen for this research not only due to the major technological advance that it represented as the first reliable meter of time, but also for its historical interest, since this timepiece embodied the theory of pendular movement enunciated by Huygens, which remains in force today. This 3D modelling is based on the information provided in the only plan of assembly found as an illustration in the book Horologium Oscillatorium, whereby each of its pieces has been sized and modelled, its final assembly has been carried out, and its operation has been correctly verified by means of CATIA V5 software. Likewise, the kinematic simulation of the pendulum has been carried out, following the approximation of the string by a simple chain of seven links as a composite pendulum. The results have demonstrated the exactitude of the clock. -

It contains nothing new except the post script. If you have already read the post, please disregard.) Hi all: In preparation for purchasing an Omega Speedmaster Professional, I have done the obligatory research on the use of the Speedmaster in the NASA space program. Chuck Maddox's excellent article on Omega's history with the Apollo program revealed some interesting facts that I did not know. In brief: The cal. 321 Speedmasters were purchased by NASA for the astronauts' use prior to the introduction of the cal. 861 movement in 1968. Apparently it is generally accepted that only the cal. 321 Speedmasters were worn on the moon during the various moon missions, as the initial procurement of these watches around 1965 was distributed to all astonauts at that time (two each) with as many as twenty still left in inventory and never used following the final Apollo 17 mission in 1972. Apparently, there is no evidence that a cal. 861 Speedmaster was worn by any of the moonwalkers or that NASA had procured any cal. -

The elevator had simply given up. What if a subway train also refused to move? I began walking seventy blocks at a time or splurging on taxis. But on this day I had taken the N train. Somewhere between Forty- ninth Street and Forty-second Street, a signal failed and we ground to a halt. For forty minutes, we stood still. An old man yelled at the conductor at full vol- ume in English and Spanish. Time and space began to collapse around me. The orange seats began to march toward each other. I was no longer breathing with any regularity. This is not going to end well. None of this will end well. We will never leave here. We will always be underground.

Technical Data Sheet RM
TECHNICAL SPECIFICATIONS OF THE TOURBILLON RICHARD MILLE RM 053 PABLO MAC DONOUGH Limited edition of 15 pieces. CALIBER RM053: manual winding tourbillion movement tilted 30° with hours, minutes and seconds. Dimensions: 50 mm x 42.70 mm x 20.00 mm. MAIN FEATURES POWER RESERVE Circa 48 hours. BASEPLATE AND BRIDGES IN GRADE 5 TITANIUM The manufacturing of these components in grade 5 titanium gives the whole assembly a high degree of rigidity and achieves excellent surface flatness which is essential for ensuring that the gear train functions perfectly. The skeletonized baseplate and the bridges have been subjected to intensive and complete validation tests to optimize their resistance capacities. It is tilted 30° providing optimal conditions for users to check the time on their wrist. Both compact and lightweight, the RM053 movement is ultra-resistant to the centrifugal and centripetal forces generated during a match. FREE SPRUNG BALANCE WHEEL WITH VARIABLE INERTIA The free-sprung balance provides better reliability in the event of shocks, movement assembly and disassembly. It also guarantees better chronometric results over an extended period of time. There is no need for an index plate, allowing more precise and frequent adjustment using 4 setting screws. FAST ROTATING BARREL (6 hours per revolution instead of 7.5 hours) This type of barrel provides the following advantages: - The phenomenon of periodic internal mainspring adhesion is significantly diminished, thereby increasing performance, - Provision of an excellent mainspring delta curve with an ideal power reserve/performance/regularity ratio. BARREL PAWL WITH PROGRESSIVE RECOIL This device permits a profitable winding gain (circa 20 %), especially during the winding start. -
