A few weeks ago, I was fortunate to come across a particularly rare and historically significant example of the Omega Seamaster 300,
reference 165024-63 S.C.
This specific example stands out as one of the earliest production models of the reference, making it an important find for collectors and enthusiasts alike,
so I thought I would share some previously undocumented information about these early examples (at least as far as I could find) .

This Seamaster 300 is powered by the Caliber 552 movement, bearing the serial number 20.309.166, which dates its production to April 22, 1964.
Given its early serial number and characteristics, it is evident that this specimen originates from the very first production batch of the reference, marking it as a key piece in the Seamaster 300 lineage.

One of the most distinctive features of this example is its ‘Slim font’ MKI bezel, which remains in exceptionally well-preserved condition, free from cracks and significant wear. This bezel type is a defining characteristic of these early models.

The dial is another point of interest. Unlike later versions, this one features a SWISS MADE designation without T markings.
This subtle yet important distinction highlights its status as one of the earliest executions of the reference.

The case of this Seamaster 300 was crafted by Huguenin Freres, the well-known Omega case manufacturer.
It retains its original, untouched mid-case, which is noticeably slimmer compared to later iterations of the 165024.
The case design shares similarities with early Speedmaster Professional models, such as the 105.012-63/64 and early -65 references, which were produced in the same era.

The caseback is another unique feature that differentiates this early sub-reference from later iterations.
It boasts a wider top bevel, a design element that was modified in subsequent production years.
A direct comparison with a 1967 caseback clearly illustrates this evolution.

Adding to the completeness of this exceptional find, the watch was discovered with its original 1506 expandable bracelet, fully linked and paired with the correct #16 end links.

Finding an untouched early Seamaster 300 like this is an exceedingly rare occurrence. With its early production details, distinctive case design, original MKI bezel, and period-correct bracelet, this 165024-63 S.C. represents an important ‘Reference Point’ in the production history and evolution of the Seamaster 300.

Interesting that my Serial is 558 numbers later, but produced 3 months early (regarding to my EoA).
