Speedy Tuesday - Omega Speedmaster Professional Caliber 863 Reference 3592.50Speedmasters With Display BackAlready way back in 1980, Omega introduced the 1st Speedmaster Professional with a display back. Quite uncommon generally speaking during that time watches . However, it turned out only available for the 18 carat gold Speedmaster Professional Apollo XI numbered edition. This has been reference 345.0802 breitling women . That watch is powered by caliber 861L movement, similar to what later would get to be the caliber 1861 movement.1985That changed in 1985. Omega started while using the caliber 863 movement, based on the same Lemania 1873 movement. However , the caliber 863 (and then 1863) are the nicer finished versions of the 861 and 1861. The first Speedmaster Professional to feature caliber 863 movement was reference 345.0808. This reference was produced between 1985 and 1990. There is a handful of variations of their reference, with a total production of approximately 2000 pieces (although not as limited editions, rather as numbered). Then, from 1989 onwards, the Speedmaster Pro with display back became regular production as opposed to numbered series.Reader's StoryYou might remember fondly the Speedy Tuesday article about the Speedmaster Mark 4.5 in NOS condition that any of us did recently. Web-sites any particular one watch, who shared his story with us, now wants to share his Speedmaster Professional Caliber 863 along. There isn't a particular story behind his purchase, other than that he simply loves the Moonwatch and was then particular reference.Speedmaster Professional Caliber 863 3592.50The Speedmaster we've got due to this week's Speedy Tuesday installment is probably the later reference 3592.50 models. Even though the 3592.50 reference number was utilized before (it's basically a successor on the 345.0808), the engravings about the display backs changed. Earlier models were engraved with 'Apollo XI', but that stopped after 1995. Also, the caliber 863 underwent some slight changes. Whereas the initial caliber 863 movements had this copper color, later caliber 863 models had a gilt finish.TritiumThis Speedmaster Professional caliber 863 incorporates a dial with tritium markers and hands. Somewhere in 1997, with all the new reference 3572.50 (and 3570.50), Omega switched from tritium to Super-LumiNova. What I experienced, could be that the tritium markers that Omega utilised in the 1990s, may be yellow-ish. It become this good patina color. It could be cognizant of look for a nice 1990s Speedmaster Pro with tritium dial and hands with box and papers. As you still can.Caliber 863As I wrote above, the caliber 863 movement had some iterations during its (production) lifetime. The caliber 863 that had been used from 1995 till 1997 had the gilt finish and 18 jewels instead of 17. In 1997, in addition to another changes while using Speedmaster Professional 3572.50 and 3570.50, the movement was updated to caliber 1863. This caliber 1863 is used today in certain display back kinds of the Moonwatch. It provides a rhodinized finish.Availability and PriceThese replica watches are offered without wasting too much effort trying to find the right piece. A good Speedmaster Professional caliber 863 reference 3592.50 from the early to mid-1990s emerged between 000 Euro. Full set, with box and papers. Don't go for less for replica watches this (relatively) early age. Within the 1980's and before, it was common to exit the boxes in the retailer or even throw them away even. In the 1990s, while using grey and red leather boxes, many people kept them. So can be capable to pick one up for only less, but check whether or not the bracelet is proper (1479 on the older ones, 1499 about the models around 1996) and whether the hands are still the original tritium ones. Later VersionsIn 1997, Omega made some drastic changes on the Speedmaster Professional 'Moonwatch' and went through the 359x.50 reference code to 357x.50. Omega calibers 1861 and 1863 were being utilized as along with a more modern style of bracelet and Super-LumiNova for many that needed lume.3573.50An interesting Moonwatch with displayback reference would be the 3573.50. It can be identical to the 3572.50 (successor in the Speedmaster Professional caliber 863) but has additionally a sapphire crystal within the front. It is sometimes named 'Sapphire Sandwich'. This model is discontinued in the intervening time, but is at the gathering from 2002 onwards. I personally had one out of my very own collection around 2004 unfortunately parted from it. Within the caseback, it comes with a particular inscription. Instead of "First watch worn around the Moon", bulova watch reviews much like the predecessors display back models, it says "The First simply watch worn about the Moon". It's well known this is not truth, there were other watch brands on the Moon also.Chocolate DialFor a little while, between 2007 and 2012, Omega also produced the 'Sapphire Sandwich' with a chocolate brown dial. This watch already had the newest reference coding, with nr. 311. The watch came using a brown leather calf strap and folding clasp. There is certainly one offered on Chrono24 for approx 300 Euro.
