Omega Speedmaster Professional Pre-Moon – Ref. 105.012-66 – DON Bezel – Caliber 321 – Iconic 1966 Moonwatch Heritage

We are proud to present this outstanding example of horological history—the Omega Speedmaster Professional Ref. 105.012-66, featuring the revered Caliber 321 and original "Dot Over Ninety" (DON) bezel. As the reference worn by astronauts during NASA’s Apollo missions, this Pre-Moon Speedmaster is one of the most historically significant chronographs ever produced.

A True Collector’s Omega – Pre-Moon, Pre-Legend

This reference 105.012-66 is a cornerstone of the Speedmaster lineage. Produced in 1966, it features the larger 42mm asymmetrical case, twisted lyre lugs, and the original “Professional” dial layout introduced for astronauts. It is powered by the legendary manually wound Caliber 321, the same column-wheel chronograph movement used in the Moon-landing Speedmasters.

This is the exact reference worn on the wrists of astronauts such as Buzz Aldrin during Apollo 11. Its design and components are iconic—the stepped matte black dial, warm aged tritium lume, and the elusive DON bezel all reflect the golden age of Omega tool-watch craftsmanship.

Condition & Features

Dial: Original matte stepped dial in deep black, untouched with rich, creamy tritium hour markers and matching hands. “T SWISS MADE T” at 6 o’clock confirming tritium usage. This is a textbook example of Omega's 1960s professional chronograph dials.

Case: 42mm stainless steel asymmetric “lyre” lug case, correct for this reference. This example is particularly rare as it was manufactured by La Centrale Boîtes (CB), one of Omega’s contracted case makers alongside Huguenin Frères. Cases produced by CB are estimated to make up two-thirds of all 105.012-66 production, and are identifiable by their flatter lug profile and more subtle transition step on the lug bevel—making them highly sought-after among collectors.

Bezel: Rare original "Dot Over Ninety" (DON) tachymeter bezel in excellent vintage condition—highly sought after by collectors for its pre-moon configuration and historical accuracy.

Crystal: Omega signed hesalite plexiglass with embedded Omega logo.

Movement: Omega Caliber 321 manual-wind chronograph, just serviced by a master watchmaker. A movement celebrated for its complexity, precision, and history—column wheel controlled and rhodium-plated. Running smoothly and offered with a 12-month mechanical warranty.

Crown: Correct original Omega crown.

Strap: Hand-crafted premium leather strap made in Belgium, custom-fitted and true to the Speedmaster’s rugged elegance.

Buckle: Omega stainless steel buckle, period correct.

Reference: 105.012-66
Serial Number: In correct range for 1966 case production

Why Collect This Watch?

Not worth the money
Color: A1-Red
My small Chihuahua loved this toy. It kept him entertained until it would stop working. He only gets about 10 minutes of play and it's no longer charged to use. I even bought a second one thinking the first one might have been just bad luck, but nope, the same problem. It seems most of these interactive toys are only given 2 to 3 stars. I'm disappointed but more importantly, my pup is even more.

Terrific product
Color: A1-Red
I adopted a 2 year old cat - she’s not much for a lot of the toys I have purchased for her, until this one! At first she seemed very cautious with it - but still followed it around - once I slowed it down (a few different options) she loves to play with it! Great purchase very pleased with it

Fun & Fast moving toy for my cats!
Color: A1-Red
This is such a fun little toy to keep my cats entertained. They were definitely weary about it for the first few days, but started to get used to it and play with it after a bit. I wish there was an even slower option because the slow option is still pretty fast, but at least it gets them up and moving. They will even play with the tail part when it's not turned on. Like others have said, it does collect hair pretty easily, but it's very easy to clean off. I don't have any dogs, but I could see smaller dogs loving this as well!

That it’s usable for more than one day
Color: A3-Pink, Color: A3-Pink
The toy itself is great and my puppy enjoyed it. My problem is that it didn’t come with a charging cord and none of mine fit. It never changed colors. Maybe if I had a charger cord it would be worth it, but right now it’s useless!!

Fun for Fido but flimsy
Color: A2-Blue
My 15 yearold mini Schnauzer, Sam, played with this for less than 1 hour and tore the rubber sleeve off it. I will say the toy itself is a genius idea. Sam was absolutely ensconced. I wish it were made sturdier.
