THE OMEGA SPEEDMASTER "MARK" HISTORY

Omega is one of the most prominent watchmakers in the world and their success can be largely attributed to the Speedmaster, specifically the Moonwatch.

It’s one of the most popular and recognizable watches in the world. Even the Rolex Daytona can’t compete with its history and importance. This is due in large part to its use by NASA, which you can read about here.

After about a dozen years and continued success, Omega started the Mark Series of the Speedmaster. Although they never made the same impact on history as the Moonwatch, the “Marks” started a trend and turned the Speedmaster from a single reference into a full line of watches.

In many ways more interesting than the standard Moonwatch, perhaps because of their lack of initial popularity, making them far more unique. Each one is slightly different than the previous iteration, which is a good thing. The series also showed that despite the success of the Moonwatch, Omega was not content with resting on its laurels, unafraid to push the boundaries of conventional watchmaking. The result was a handful of interesting references, showcasing Omega’s ability to maximize creativity while still maintaining quality.

Its Perhaps important to reference the Mark IV,s Predecessors before we get to the MARK IV itself and the why will become apparent soon.. So lets do that

MARK II

First up in the ‘Mark” Series is the Speedmaster Mark II. In 1969, Omega not only sent their watch to the moon, they also made their first major departure from the standard Speedmaster line with the Mark II, which was produced until 1972. The Mark II was the first in the series and there is actually no official “Mark I”. Omega intended it as a follow-on to the Moonwatch — hence, the second “mark” or iteration — but NASA was not in need of a new version.

Mark II

Internally, it was the same as the Moonwatch with the manual winding Caliber 861. This one was fitted with a mineral crystal, internal tachymetre bezel, and a streamlined case that fit right in for the time period. It was a solid step forward for Omega that showed ingenuity and progress without going too far off the deep end.

If you want an extremely well made and affordable vintage watch that you don’t see every day, look no further than the Omega Speedmaster Mark II. I personally think the Mark II with racing dial is one of the coolest vintage chronographs out there. Since the Mark II has been re-issued by Omega, now’s an excellent time to grab one of the originals.

The above we will be listing later this week!

MARK III

The Speedmaster Mark III came along in 1971 and was in production until 1973. Being the first Speedmaster with an automatic movement, the Mark III was a significant improvement for the line. The Caliber 1040 is a two-register chronograph movement, which came out (like the 321 and 861 calibers) of a joint venture between Omega and Lemania. Two years after the Mark III release, the Speedy 125 took the Caliber 1040 one step further by making it Omega’s first automatic chronograph to receive the certified chronometer label.

Finally we Get to the MARK IV

The Mark IV was released in 1973, was produced only through 1974, and is somewhat of an amalgamation. With a case based on the Mark II and the Caliber 1040 movement found in the Mark III, it’s a wonder what Omega’s intent was with the Mark IV.

But this unusual Reference is not as easy to come by as you may thing particularly finding models in GOOD & ALL ORIGINAL condition

IN THE SHOP

The Case

Large even by modern standards 41.9mm in diameter (excluding crow / pushers) 45mm (inclusive) 45mm lug tip to lug tip and 22mm lug spacing Big Dial diameter of 36mm makes for excellent read clarity Dial visible under the Original flat mineral crystal. Fully Signed Screw down case back light hippocampus inscription has worn with age but watch is importantly UNPOLISHED

Featuring ALL original Radial Brushed finish to case front with polished beveled edges & brushed sides

Original Omega Ω Signed flat crown & original 1973 pushers (not a latter service replacements)

BUYER BEWARE: Mentioning the UNPOLISHED maybe a fair warning on "Shiny Watches" Of course NOS (genuine New Old Stock) watches hold a prized place in collections but legitimate examples are VERY rare what to look for second is Original finishes yes these may be scuffed here scratched there but importantly UNPOLISHED is what a serious collector is looking for theres plenty of "shiny" examples out there overzealously polished watches lacking definition and edges. A serious collector will give a "Shiny" watch a wide berth..

The hippocampus is a legendary creature from ancient Greek mythology and basically means “sea-horse monster” – Poseidon, god of the sea used them to drive his chariot over the waves, so they’re part horse, part fish, much like an Iceland frozen paella.

A seahorse emblem has graced the casebacks of this line since 1958 as a symbol for water-resistance, and is now one of the best-known trademarks in the world of watches. The logo was conceived by engraver Jean-Pierre Borle, who was inspired in Venice by an image of Neptune, the Roman god of the sea, driving a chariot pulled by seahorses (this is why the Omega seahorses wear bridles).

The Dial

The Speedmaster Mark IV uses the inner crystal as a fixed tachymetre scale with "the rest" of the dial visible beneath this gives an additional sence of "depth" to an already chunky cased watch.

Classic High visibility contrast dial designed much like a pilots instrument panel to give maximum read clarity at a glance

Using Omega calibre 1040/ Lemania 1340–a two-register chronograph. the MK IV featured a date display and a central chrono minute hand similar to the legendary Lemania 5100. (often leading this watch to be mistaken for a 1045 speedmaster)

There is a conventional 12-hour chrono totalizer sub-dial at 6 o’clock, and a unique running seconds and 24-hour indication on the sub-dial at 9 o’clock. with the tachymetre scale on an inner bezel.

The Band

22mm As anyone who has ever searched for a 22mm Omega strap will know finding one of these is no meen feat tho few cases use a 22mm steel strap (the Speedmaster here the flightmaster etc) this is one of them Despite Omega database (see " https://www.omegawatches.com/planet-omega/heritage/vintage-details/14296/ ") we have on good athoroty that this watch was indeed suplied with the 22mm Holzer Strap being Listed with this watch and
