1973 Omega Anniversary
Speedmaster 125 Chronometer



This is a photo study and review of the 1973 Omega Speedmaster ‘125’ Automatic Chronometer/Chronograph.

1973 Omega Anniversary Speedmaster 125 Chronometer 125-a

I won this Omega a few days ago on eBay. I was the only bidder. The seller shipped it on Presidents Day via UPS Overnight. I received it late Tuesday, February 22nd.

OVERVIEW
To celebrate its 125th anniversary, Omega developed a very special commemorative watch - - a watch that embodied the highest standards of craftsmanship in Omega watchmaking. This watch was the Speedmaster ‘125,’ limited to just 2,000 examples.

The Speedmaster ‘125’ was a tour-de-force of its day, becoming the very first automatic chronograph to be COSC-certified as a chronometer. Other firsts for the ‘125’ included:

• First automatic chronograph with calendar.
• First watch with a tempered mineral crystal (sapphire was not available in such a large size).

The Speedmaster ‘125’ was unique among Omega watches in that it was the first time Omega designed and produced a limited edition commemorative anniversary watch. Further, the ‘125’ is the only Omega to use a case, a bracelet, and a movement never used in any other Omega watch.

As of early 2011, the cost of a Speedmaster ‘125’ in excellent condition can range from $2,000 to $5,000.

CASE
The Speedmaster ‘125’ is honed from a huge steel billet, measuring 42mm (excluding crown) x 51.5mm. The entire watch weighs in at a hefty 182.9 grams. Although the dial is round (Ø=35mm), the case is tonneau-shaped, with rounded top and bottom segments. The steel case is very thick: the main body is approximately 10mm thick at the center of its length, and about 12mm thick at the lugs. The bezel and caseback bring the overall thickness to 15mm. The bezel is actually separate from the case itself, and can be removed along with the movement as one piece.

The caseback bears the embossed “Speedmaster” logo; there are no limited edition numbers showing on any ‘125’ casebacks.

1973 Omega Anniversary Speedmaster 125 Chronometer 125-c

In addition to the usual logos and information, the inside caseback on the ‘125’ is stamped with the case reference numbers of 3780801 and 1780002.

1973 Omega Anniversary Speedmaster 125 Chronometer 125-d

The Speedmaster '125' was originally rated at 60 meters of water resistance, but should no longer be considered water resistant due to aging of the gaskets and seals.

BRACELET
The “bar” style bracelet is integrated with the case of the ‘125,’ which cannot be substituted with a strap. The bracelet is unique to the ‘125,’ and is 5.5mm thick at the lug and 3.8mm thick at the buckle. The bracelet is 26mm wide at the lugs and 15.5mm wide at the buckle.

1973 Omega Anniversary Speedmaster 125 Chronometer 125-e

The bracelet utilizes an Omega No. 11 stainless steel clasp, and bears the reference 1221/212.

The buckle is a single locking type, and is engraved and embossed with the Omega logo at its tip. The bracelet is quite long, appearing to handle up to an 8.5” wrist. Only the two smallest links are removable, each link measuring about 11/32” in length. In addition, the buckle has eight micro-adjustment holes, which measure a total of 13/16” in further adjustment. Four years following release of the Speedmaster ‘125,’ Omega began offering an alternative bracelet (“1225/212”) that looked the same as the original from the top, but distinctively different from the underside.

DIAL
The round dial on the ‘125’ is 35mm in diameter, excluding its polished steel housing.

Beneath the crystal, a white-on-black tachymetre surrounds the dial in an elevated position. The main surface of the dial is approximately 3mm below the tachymetre, and is a dark gray matte coloring. The dial features a raised steel Omega logo, name, and model name (“125”). The name “Speedmaster” is painted in white. At certain photographed angles, the raised steel components become almost invisible, or even appear black in color. The dial also is painted with the words “AUTOMATIC CHRONOMETER” and “T SWISS MADE T.” The dial includes a date window at the three o’clock position, and two sub-dials: one at six o’clock and one at nine o’clock. There are four central hands: hours, minutes, chrono seconds, and chrono minutes. The six o’clock sub-dial contains the chrono hours register, and the nine o’clock sub-dial includes both a small seconds hand and a non-adjustable 24-hour hand. The two chrono pushers on the right side of the case operate the chronograph functions in the normal manner. The crown offers three positions, including a quick-set date function at the middle detent. The Speedmaster ‘125’ offered three alternative perimeter registers (in addition to the tachymetre): telemetric, pulsimetric, and decimal.

MOVEMENT
The specially-designed and manufactured caliber 1041 movement introduced in the Speedmaster ‘125’ was the very first automatic chronograph to be COSC-certified as a chronometer.

The movement was derived from the Lemania 1341 and is an enhanced version of Omega’s mainstay 1040. The 1041 features 22 jewels, a heavy platinum-ringed rotor, and was “adjusted” at the factory for accuracy in five positions plus temperature variability. Differences from the caliber 1040 include the plate, rotor, and chronograph bridge. The caliber 1041 is Swiss made, measures 31mm x 8mm, operates at a frequency of 28,800 bps, utilizes Incabloc shock protection, and has a rated power reserve of 44 hours.

ON THE WRIST
The Speedmaster ‘125’ is a BIG watch, even by 2011 standards. However, on the wrist it only feels “big” in its height. The case is tall, at 15mm, and would be difficult to fit easily under the cuff of a dress shirt.

1973 Omega Anniversary Speedmaster 125 Chronometer 125-j

Since the long tonneau case carries so much mass it feels slightly top-heavy, especially considering the bracelet is only 15.5mm wide near the clasp. Other than that caveat, the ‘125’ feels quite natural and comfortable on the wrist. The bracelet design is great for not pinching or pulling wrist hair.

1973 Omega Anniversary Speedmaster 125 Chronometer 125-k

The bold white hour and minute hands make viewing the time easy, but could be easier if the other two central hands were just a tad narrower. I happen to be a big fan of red on a dial and would have appreciated if either the small seconds hand or the “Speedmaster” name were rendered in red (or even orange).

Operation of the chrono pushers and three-position crown is easy, smooth, and sure. Chrono hands snap back to zero as they should. Although the clasp and buckle are only single-locking, the mechanism has a safe and secure feel.

Lume is still bright, particularly on the white-lumed hour and minute hands.

Following a UPS shipment, the watch is running about +16s/d, not bad for a 38 year-old watch. I’ll keep checking over time and employ the fine adjustment screw to tweak the timing if necessary.

WOW. Amazing watch, picture, and review. So glad you snagged this one. The only thing I do not like is the amount of taper on the band. Beyond that, a SUPER winner. I'll admit it. . .I've been trolling for one since you showed yours. . . Thank you for sharing this with us Tom.

Shocked 1973 Omega Anniversary Speedmaster 125 Chronometer 46145 Tom, you may have outdone yourself this time around with your Omega Anniversary
Speedmaster here ! Smile Not only is this one of the NICEST watches, but it's the kind of watch
that stands as a signature piece in a collection. It will fit PERFECTLY into your collection sir.
Yowza !!! Just might run out of adjectives to describe this one with ! cheers Also have to add
that your review was so thorough, and detailed that it's hard to believe. One thing is for certain.
THIS is one of those watches that reaches an EPIC level imho. It has everything that makes
people who love this hobby happy. The name on the dial, the quality, the design, as well as
the cool limited edition, AND vintage factor ALL bring this watch to a very different level. The
first thing that you mentioned that really was surprising ws how you were the only bidder.
That is REALLY something, but it looks like that turned out to be a good thing, because I can
imagine what it would have been like if more people had known about it, and been bidding also.
In any case, congratulations on picking up this epic piece. Truthfully can't recall seeing other
watch cases that look like this special Omega here Tom. Like you are saying, it is a tonneau,
but it has an entirely different feel, or persona to it. Guess it's just the Omega style added in
or something, but this is IMPECCABLE right here !!! 1973 Omega Anniversary Speedmaster 125 Chronometer 46145 The area around the case is so beautiful
with it's shape, and the brushing is again on such a high level that it's hard to pull your eyes away.
You could end up staring at the shapes, as well as brushing, and then forget about the time
completely. Even when you discover how the sides of the case are done, you are in awe. The
various angles of the watch set this watch off, and manage to stop you in your tracks at every
corner. Whether it's a view from the top, or the sides, this watch is simply BREATHTAKING !
To me it would be a centerpiece type of watch, and I think it is. Must be something very very
special to see this watch with ALL of your other unforgettable watches. cyclops Just the whole style,
along with brand name, and limited edition factor must take this one near, or at the top. Truthfully,
just can't say enough about a watch like this. Every aspect surpises with it's own special personality,
or feel, that all comes together in such an enjoyable way. I mean the case alone is the ULTIMATE
vintage masterpiece by itself. However, how about the dial sir ?! It also has some of the most
unforgettable traits. The tachymetre section, and how it's raised above the dial is one part. Just
the manner it which it is separated, and is also that classy black, contrasting with the gray dial is
exquisite I think. Speaking of that gray dial. It REALLY compliments the entire case finish, as well
as the bracelet. Even the four separate hands that you mentioned seem to become more beautiful
against this dial. Same thing goes for the various sub-dials, and how they add even more exhilaration
to the watch. The hands, the sub-dials, the tachymetre, and even writing on the dial is done with
such care, and respect, it's unbelievable. Actually, it's hard to imagine a watch being ANY better
than this vintage Omega Tom. Very Happy It's the ULTIMATE watch ! Even the case-back is breathtaking,
with it's distinctive logo, and of course workmanship. That bracelet is unlike any other bracelet as
well, with it's large brick-like links, and exceptional craftsmanship. Honestly, it's this craftsmanship
that seems to take this watch to such a high level. The Grand finale of all of it, might just be
the movement. Each detail, each decoration, and piece of it is BREATHTAKING, which is one of
the themes of this ULTIMATE watch sir. Congratulations on winning such an outstanding watch,
and I really hope you enjoy it for many many years to come.

Breathtaking watch, photos, and REVIEW !
