When Omega presented its Speedmaster Professional Moonphase in 2003, it wasn’t a totally new model. Effectively back in 1985, Omega presented the SpeedyMoon 385.0809 and two extra references. The 2003 model, reference 3876.50 for the calfskin lash rendition and 3576.50 for the one on the arm band, depends on the 1980s SpeedyMoon.

In this article, I will have a more intensive glance at the presently ended Omega Speedmaster Professional Moonphase 3876.50 and attempt to clarify why it is misjudged, as I would see it. It has been ended since 2018, so you should scan the used market for one or attempt to contact some approved sellers who actually may have one in stock. This Speedmaster Professional 3876.50 is almost indistinguishable from the typical Moonwatch, yet with an alternate development, and dial obviously. The 3876.50 has a moonphase marker at 12 o’clock, just as a pointer date indicator.

What is the purpose for the stopping of this Speedmaster Moonphase reference, and for what reason is it considered unloved?

Speedmaster Professional Moonphase 3876.50

For a period of time of roughly 15 years, Omega had a Speedmaster Professional Moonphase in its assortment. During that time, Omega additionally added a few varieties to the Speedmaster Moonphase. Recall the fleeting variant with an aventurine dial? Or on the other hand the Speedmaster Co-Axial Moonphase? Lovely watches, however either too enormous or simply not thought about a Speedmaster Professional “Moonwatch”.

The 2012 Speedmaster Moonphase reference 311. with an aventurine dial was particularly exceptionally noteworthy. Authoritatively, that was a “Professional” model also, regardless of the 44.25mm case (rather than 42mm). It was immediately ended, the motivation behind why remains unknown.

Speedmaster Moonphase Aventurine

A few years after the fact, Omega added a couple of more Speedmaster watches with Moonphase complication. Additionally housed in the 44.25mm cases, in steel, valuable metals, and in ceramics. These were completely fueled without help from anyone else twisting in-house created developments, and one of them highlighted an aventurine dial (again).

The Master Chronometer rendition, in the image underneath, with aventurine dial, is alluded to as the “Blue Side of the Moon” and has reference number 304. With a retail cost of €13,700. It isn’t even the most costly model of the assortment. That would be the Speedmaster Moonphase Master Chronometer models in platinum, with a ruby set dial like the reference 304., with a cost of €53,800. Nonetheless, the hardened steel Speedmaster Moonphase Master Chronometer ref. 304. beginnings at €10,100.

Caliber 1866

For the Speedmaster stalwarts however, I will in general accept that the 42mm Moonwatch-based Moonphase models, regardless of whether that’s the first SpeedyMoon 345.0809 or the 2003–2018 Speedmaster reference 3576.50 and 3876.50, are the most fascinating ones to our perusers and Speedmaster fans.

So back to the Speedmaster Professional Moonphase 3876.50 that we have here for you today. Fitted with the Lémania based type 1866 development, it offers similar capacities as the standard Moonwatch, yet with an additional schedule and moonphase pointer. The first Omega SpeedyMoon utilized the archetype, the type 866. The 1866 development utilizes type 1861 however added with a module for the extra functions.

The lunar complication for the Speedmaster 3876.50 works like most other moonphase complications we see out there. A circle with two moons imprinted on it is associated with the schedule component. Subsequently, it makes a full pivot in 59 days. A lunar month requires roughly 29.5 days (actually you need to add 44 minutes and 2.8 seconds to that), that’s where the 59 days comes from. For the situation band, as can be found in the image underneath, there are two correctors. One is to propel the date, the other to address the moonphase indicator.

First and Only Watch Worn on the Moon

What I generally discovered intriguing about the Speedmaster Moonphase 3876.50 and different variants with a sapphire case back, (for example, the reference 3573.50 and the earthy colored dialed reference 311. is the etching “The First and Only Watch Worn on the Moon”. Some other Speedmaster models with a sapphire case back don’t have the “And Only”. These ones do, nonetheless. Furthermore, the most odd thing is the means by which little sense it really makes…

We realize that different watches were utilized on the outside of the moon. For instance, Apollo 15 space traveler Dave Scott really wore a Bulova chronograph on his wrist while doing a moonwalk in 1971. We talked with Apollo 15 Dave Scott in this article, some time ago .

So why Omega actually utilized “And Only” for such a long time for these situation backs? One clarification may be the way that the Speedmaster was only the unrivaled watch qualified by NASA to be utilized during EVA. Another clarification is that this was finished accidentally under the lead of Jean-Claude Biver in those days at Omega. He is, all things considered, known to be intense. Extremely intense. Maybe it presents the defense back more intriguing with this little chronicled error.

Close to the first SpeedyMoon

As you can see, the Speedmaster Professional Moonphase 3876.50 is fundamentally the same as the first SpeedyMoon reference 345.0809. The moon on the circle is unique, however the fastest giveaway that you’re managing either the new or the old form are the edges around the subdials on the advanced Speedmaster 3576.50 and 3876.50 references.

Taking a more intensive look, you will see that the date-dial numbers somewhere in the range of 9 and 21 are the alternate far up from their partners on the first SpeedyMoon. Intriguing to know is that numerous redials of the SpeedyMoon do show those numbers like the advanced Speedmaster Professional Moonphase: not topsy turvy. The utilization of tritium on more established models is obviously additionally an unmistakable giveaway, shown by the “T Swiss Made T” at 6 o’clock on the dial.

Beautiful however unloved

The SpeedyMoon from the 1980s ( that we shrouded in this article on Fratello ) is a profoundly pursued model, that has become a costly Speedmaster to pursue. Back in 2003, when the new Speedmaster Professional Moonphase 3876.50 was presented, the first SpeedyMoon wasn’t however costly as it seems to be today obviously, yet absolutely more important than the cutting edge Speedmaster Moonphase 3876.50 at retail. Since it has been ceased, the costs are as yet normal. Entirely sensible in reality, indeed. They are in the ballpark of €5,500 Euro or $6,000. At that cost, you ought to have the option to discover one in flawless condition. Incredibly, it isn’t excessively far from the watch’s last retail price.


I realize that very few Speedy lovers and authorities are after one. Essentially, not very many have it in their assortment (I don’t have one in mine, for instance). Nonetheless, I wouldn’t mind possessing one eventually. The Omega Speedmaster Professional Moonphase 3876.50 imagined in this article is in my partner Gerard’s assortment. He prefers the first SpeedyMoon better however doesn’t mind possessing this advanced rendition for sure.

Although the extra subdial gives the dial an altogether extraordinary dynamic, I actually feel it is a genuine Speedmaster Professional. Simply from a collector’s angle, I lean toward this 3876.50 more than one of the Moonphase Master Chronometer versions.  The stopped 44.25mm Speedmaster Professional Moonphase with Aventurine dial may be intriguing to have in light of the fact that it is so uncommon. Be that as it may, the width puts me off a piece, as does the type 1866 dial design. The solitary Speedmaster moonphase that I would like over this cutting edge one, is obviously the first SpeedyMoon from the 1980s.
