Βιδωτή ξεβιδωτή, από τη στιγμή που αντέχει σε κολύμπι, η υγρασία και η βροχή είναι άνευ σημασίας

δεν ειναι ακριβως ετσι,σου εξηγησα παραπανω ,τι παιζεται..αλλα οτι και να λεμε δεν θα βγει ακρη,θυμαμαι ακομα οταν ειχαμε τον διαξιφισμο για το moon με τα fortis...την οποια θεωρω ατοπη συγκριση...

Μάλλον ούτε στις δικές σου επιλογές αγοράς είναι το moonwatch, ειδάλλως θα το είχες.


η ομεγα το 69 προτεινε στην ΝΑΣΑ,ενα αναβαθμισμενο μοντελο,για να αντικαταστησει ,το σε ολους γνωστο moonwatch...το ονομα αυτου?ΜΑΡΚ ΙΙ ...η ΝΑΣΑ ,απο την στιγμη που ειχε ηδη ενα τεσταρισμενο ρολοι ,δεν ειχε χρονο για χασιμο και ειπε οχι ευχαριστω...το 1ο speedmaster του chuck ηταν ενα ΜΑΡΚ ΙΙ .η ομεγα μπορει να ειχε τεσταρει η ιδια την αξιοπιστια του νεου μοντελου ,αλλα αυτο δεν λεει τιποτα ,εαν δεν το εκανε επισημα η ΝΑΣΑ
μεταξυ των αλλων στο ΜΑΡΚ ΙΙ ,ειχαν αυξησει την υδατοστεγανοτητα στα 120 μετρα..
και κατι ασχετο ,που για σενα μπορει να μην λεει τιποτα,το δικο μου ειναι παραγωγη 71  και βγηκε απο το αμερικανικο εργοστασιο

επελεξα να αγορασω για αρχη ενα vintage speedy,το οποιο θα ηταν ο αντικαταστατης,το οποιο εχει την 861 με μεταλλικο φρενο,το οποιο εχει τις ιδιες  προδιαγραφες ... ,αποδεχομαι την ιστορια του moonwatch  ,την θεση του και την πορεια του....και φυσικα θα αγορασω και το 3570.χχχχ, διοτι το θεωρω ενα εξαιρετικο ρολοι/μηχανη σε αυτα τα λεφτα ,ολοι οι αλλοι απλα το κοιτανε
οπως ειπα και αλλου,την μαμα μηχανη την φορεσε και μεγαλη κυρια...με αποδειξεις παντα στο αναλογο θεμα...
εαν σου κανει κλικ το moonwatch το αγοραζεις ,οπως και να χει ,εχει αποδειξει την αξια του και οτι καποια αλλα ,απλα βλεπουν την σκονη του

ειναι σαφες?

Almost surely an Omega Speedmaster Professional. It's the only watch NASA has approved for extra-vehicular activities. Even the Omega X-33 is only approved for internal space mission use, not EVAs.
Even Cosmonauts use the Speedmaster Pro. I've heard that every Russian spacesuits come with a Speedmaster attached as part of the standard gear.
The whole Fortis Official Cosmonaut watch thing is more marketing than anything else. Fortis provides watches to Cosmonaut trainees, and some may be used in space, but when it comes time to go out the airlock, Cosmonauts wear Speedy Pros.

Interesting thing is, it was a Soviet designed chronograph, a Strela with the Poljot 3033 movement, that was the first watch worn in the vacuum of space. Alexei Leonov had it strapped it to his space suit during the first ever spacewalk in 1965..
αυτο το ειχαμε ακουσει ,αλλα οπως λεει και ο τυπος:θελω να τ'ακουωωωωωωωωωω   
I did a little search and came up with this,... For over 40 years, the Omega Speedmaster Professional has been the only watch qualified by NASA and the Russian Space Agency to be used while on space walks. All astronauts wear an off the counter Speedmaster on a velcro band over their space suit.

Dear Sir,
In reply to your net inquiry dated Febr. 19,1999 here are some details:

1. it is obvious that the first moon landing was made with a Speedmaster fitted with a caliber 321 movement. The toward the seventies, the NASA has probably also used the replacement movement caliber 861.
We have no official confirmation of what has been used and when, except for the first Moon landing.
2. The re-qualification in 1978 is exclusively made with the caliber 861.

Kind regards

Some watches are more than only timepieces. FORTIS without doubt is one of the Swiss watch brands whose watches are admired not only because of their mechanical inner values. With the probably longest time in weightlessness these space proven watches have a fixed position on the wrist of pilots space travellers in their in the hard daily life and on board the international space station ISS orbiting the Earth.

International Space Station Imagery
 

 ISS018-E-039241 (10 March 2009) --- Cosmonaut Yury Lonchakov, Expedition 18 flight engineer, participates in a session of extravehicular activity (EVA) to perform maintenance on the International Space Station. During the 4-hour, 49-minute spacewalk, Lonchakov and astronaut Michael Fincke (out of frame), commander, reinstalled the Exposing Specimens of Organic and Biological Materials to Open Space (Expose-R) experiment on the universal science platform mounted to the exterior of the Zvezda Service Module. The spacewalkers also removed straps, or tape, from the area of the docking target on the Pirs airlock and docking compartment. The tape was removed to ensure it does not get in the way during the arrival of visiting Soyuz or Progress spacecraft.

Στην επισημη φωτο ο Yuri Lonchakov ,εχει το φορτις,αλλα μεσα στον σταθμο φοραει ενα αλλο ρολοι(ομεγα).Εσυ πιστευεις ,οτι αλλα ρολογια ,δεν θα μπορουσαν να περασουν τα τεστ των Ρωσων?Γιατι τι λεω?Εχουν μια μηχανη (ΕΤΑ 7750),οπως πολλοι αλλοι,χωρις μετατροπες...Δεν γνωριζω να γινονται αλλες αλλαγες ,στην κασα ,αρα πολλα αλλα ρολογια θα μπορουσαν ναι ειχαν επιλεχθει...Ακομα δεν εχω καταλαβει,γιατι λοιπον ,η επιλογη τους ηταν τα Φορτις?Μηπως η Φορτις πηγε στους Ρωσους?Γιατι αφου εχουν επιλεξει επισημα φορτις, συνεχιζουν να φορανε ομεγα?

The Speedmaster was later subjected to additional gruelling tests on board the Russian space station MIR between July 1993 and July 1994. The success of these exceptional endurance tests was attested by a certificate initialled by the MIR crew. The OMEGA Speedmaster had become the most tested watch in the world.



Russia's pioneering space station MIR was again used as an orbiting test laboratory in 1998 for OMEGA's X-33 multifunction chronograph. After successful completion of the tests, MIR also offered a unique opportunity to introduce the watch to the public via a live satellite link-up with the Houston Space Center.
The Speedmaster X-33 has been flight-qualified by both NASA and the Russian space agency and is part of the standard equipment avaliable to all astronauts and cosmonauts. However, the legendary OMEGA Speedmaster Professional also remains the only watch certified for extra-vehicular activity.

Τι την θελουν την Φορτις,αφου εχουν το πιο δοκιμασμενο ρολοι?Γιατι να μπουν στην διαδικασια νεων δοκιμων?Δεν εχει νοημα..
Μηπως γιατι ειναι σπονσορας?

Η ΝΑΣA εψαχνε ρολοι,μιλαμε για την δεκαετια του 60...αλλες εποχες και φυσικα τεχνολογιες..οτι ρολοι πηγε σαν υποψηφιο τοτε ,δεν ηταν τυχαιο.Σε αυτα τα τεστ ,το ομεγα κερδισε,τοσο με την 321 ,οσο και με την 861


Η ομεγα παρουσιασε στην ΝΑΣΑ το MARK ΙΙ ,σαν αντικαταστατη,αλλα η ΝΑΣΑ,ειχε ηδη ρολοι και δεν θα εκανε νεες δοκιμες,χασιμο χρονου.Το διαστημα ηταν ο προσανατολισμος τους και οχι να τεσταρουν ρολογια!Οι Ρωσοι μετα απο αυτους υιοθετησαν το moonwatch και το δοκιμασαν,ολα οκ..

MARK II

we know that in February 1969 our US Agent and our Sales Manager paid a visit to the NASA in Houston and proposed the Mark II as an alternative to the already in use and most appreciated "moon watches". This proposal was denied because the Apollo program had tight schedules and that it would have taken too much time to the NASA to get the official approval from the Test Division.

και για ενα απο αυτα ,υπαρχει μια ιστορια,οτι ηταν και σε EVA...





From Apollo XV, astronaut David Scott:

142:14:22 Scott: "Verify cabin at 3.5." Okay, cabin's at 3.5. Suit circuit's locked up at about 4.4. My PGA is coming through 5 and decaying. And let's slip on a watch.
[Dave may have had his watch hanging from the instrument panel and, in any event, he is now putting it on and is probably starting the stopwatch function.]
[Scott, from a 1996 letter - "I do not recall ever having looked at my watch after egress. In the cabin after EVA-2, I noticed that the crystal of my Omega had popped off sometime during the EVA. Therefore, on EVA-3, I used my backup Waltham watch (which was) of a similar type. It worked just fine during the even higher temperatures of EVA-3

H omega εθαψε το θεμα,γιατι δεν ηταν υπερ της...το ρολοι φοραγε μια 7734,οσο θυμαμαι και οι τιμες του ειναι καλες,οταν το εψαχνα πριν 2 χρονια..

NASA Aims for Moon by 2018, Unveils New Ship



The last lunar landing was during the Apollo 17 mission in 1972.

The new plan will cost about 104 billion U.S. dollars over the next 13 years and help President George W. Bush achieve the vision for space exploration that he outlined on January 14, 2004. At that time Bush said he wanted humans back on the moon by 2020.

The centerpiece of NASA's return to the moon is a new spacecraft dubbed the Crew Exploration Vehicle (CEV). The CEV (see photo) is designed to carry four astronauts to the moon for stays of up to seven days—until a moon base allows for longer expeditions (watch NASA animation depicting a future moon mission).

The spacecraft can be piloted remotely. It can also be configured to ferry cargo loads and crews to the International Space Station and may eventually carry up to six astronauts to Mars.

NASA did not establish a timetable for missions to Mars in the announcement, which was made today in Washington, D.C.

"Apollo on Steroids"

The CEV will be shaped like the capsules used during NASA's Apollo program but will be three times as large.

"Think of it as Apollo on steroids," NASA administrator Michael Griffin said at a press briefing as he unveiled plans for the CEV, according to the Associated Press.

On its return trip, the CEV will be able to parachute to dry land or water, though land is preferable. With proper heat shield replacements, the craft will be able to be reused up to ten times.

Why aren't the Speedmaster Moonwatch and X-33 Mars watch more water resistant than 30 meters?



The Speedmaster Moonwatch and X-33 are only water resistant to about 30 meters. This leads many owners to ask why OMEGA chose to not give them greater water resistance. But additional water resistance is not always an advantage.

Highly water resistant watches are designed to handle environments where the air or water pressure outside the watch is greater than the pressure inside the watch. A diving watch like the Seamaster Professional series that is rated to 330 meters can handle an external pressure of up to 30 times the watch's internal air pressure. The Speedmaster Moonwatch and X-33 are rated for 30 meters, or only about 3 times their internal pressure.

But pressure works both ways. Yet none of the normal water-resistance features allow a watch to handle excessive internal air pressure, which can occur using most any form of pressurized environment--a deep diving chamber, a spacecraft or even in a commercial jetliner.

•In a deep diving chamber using a helium rich air mixture, helium--the smallest molecule--seeps past the seals, allowing the watch's internal pressure to gradually equalize to the chamber's pressure. During decompression of the chamber, the helium cannot seep out fast enough, causing the pressure in the watch to exceed that outside of it.
•A watch on the outside of the astronaut's spacesuit will be exposed to little or no air pressure when he steps out for a spacewalk or on the surface of the moon.
•In a commercial jetliner, you are in a pressurized cabin because the air pressure at high altitudes is very low. On rare occasions, the cabin pressure may drop suddenly, causing the pressure inside the watch to be greater than outside of it.



The end result is that due to any these several reasons, the air pressure inside the watch becomes greater than the air pressure outside the watch. The tigher seals of a highly water resistant watch can prevent these pressures from equalizing as quickly as they might change in the environment. The weakest seal for handling internal pressure is that holding the watch's crystal. When internal pressure exceeds that seal's limits,
the pressure will escape by causing the crystal to pop out.



This is why the Speedmaster Moonwatch and X-33 are not made waterproof to great depths. These air pressure difference issues occur in routine space mission events, rendering a watch that cannot handle them a danger to the mission.
