The Omega Speedmaster reference 105.002, a transitional model produced for a remarkably short period, represents a fascinating chapter in horological history. Jlc.thomsen's recent acquisition of a pristine example with alpha hands and an original bracelet offers a rare glimpse into this elusive reference. His detailed account not only showcases the watch's unique characteristics but also highlights the serendipitous nature of vintage watch collecting.
Was super happy to find this fantastic example of the transitional 105.002
Not many are aware of this reference which production lasted less than a year, some say 6 months.
Identical to the 2998-62 although some 105.002 were also fitted with baton hands like the later 105.003. But to find one with alpha hands and in this pristine condition and an original bracelet with almost zero stress. The engraving on the back is still super clear too.




That silver rehaut around the dial, like on the 2998 just give it so much depth.
The story on how I got it is just as spectacular. I was picking up a Minerva at my Vintage watchmaker’s workshop, chatting and showing him some incoming vintages I was working on.
He told me about this Speedmaster that he had kept for a friend in his vault, in case anyone would be interested.
His friend had bought it more than 20 years ago on a flee market for 600 euros. He just thought it was a fun watch to have, but was not really interested in watches and never really wore it. At one point he had asked my watchmaker if it was worth selling. When he heard the price he immediately asked him to take it in commission and sell it. He didn’t promote it too much and waited for an enthusiast to show up.
That turned up to me! I bought it on the spot and put down a deposit in February. Now it’s here and it’s real.
I just love it!

About the Omega Speedmaster Ed White Ref. 105.003
The Speedmaster reference 105.003 is notable for its straight-lug case design, a characteristic that distinguishes it from later Speedmaster iterations which adopted twisted lugs. This reference is often recognized by collectors as the last Speedmaster to feature this specific case architecture before the introduction of crown guards and a different lug profile. It represents a transitional period in the Speedmaster's design evolution, maintaining a direct lineage to earlier models while incorporating subtle refinements.
This reference houses the Omega Caliber 321, a column-wheel chronograph movement, known for its robust construction and serviceability. The stainless steel case measures 39 mm in diameter, presenting a balanced proportion on the wrist. It is fitted with a Hesalite crystal, a material chosen for its shatter-resistant properties. The watch offers a water resistance of 50 meters and a power reserve of 48 hours, suitable for daily wear.
For collectors, the 105.003 holds significance as a pure expression of the Speedmaster's early design principles. Its straight-lug case and Caliber 321 movement are highly sought after, appealing to those who appreciate the model's historical progression. Variants primarily concern dial and hand configurations, though the core specifications remain consistent across its production run, solidifying its place as a key reference within the Speedmaster catalog.

About the Omega Speedmaster Ref. 105.002
The Speedmaster reference 105.002 represents a transitional period in the model's early production, bridging design elements between the earlier 2998 series and the subsequent 105.003. Its production run was notably brief, estimated to be less than a year, making examples of this reference less commonly encountered. It shares many visual characteristics with the 2998-62, distinguishing it as an early iteration within the broader Speedmaster lineage.
This reference typically features a stainless steel case housing the manual-winding Caliber 321, a column-wheel chronograph movement. The case diameter measures 39.7mm, a size consistent with early Speedmaster models. The crystal is made of Hesalite, a common material for tool watches of its era, known for its durability and resistance to shattering.
Collector interest in the 105.002 often centers on its transitional nature and the specific hand configurations observed. While some examples were fitted with baton hands, those retaining the earlier alpha hands, similar to the 2998, are particularly sought after. The presence of an original bracelet and clear case back engravings further enhances its appeal to collectors focused on originality and condition.
