The Speedmaster reference 145.012 represents a significant iteration within the model line, marking a transition point in its design and production. This reference is notable for being among the last to feature the revered column-wheel chronograph movement, a characteristic highly valued by collectors. Its design maintains the classic proportions and aesthetic that define the early Speedmaster chronographs, preceding later design updates.

This reference typically features a stainless steel case with a diameter of 42 mm, housing the manual-winding Caliber 321. The crystal is Hesalite, contributing to its period-correct appearance. Water resistance is rated at 50 meters, suitable for everyday wear. The fixed tachymeter bezel surrounds a black dial, offering clear legibility for its chronograph functions.

For collectors, the 145.012 is particularly appealing due to its use of the Caliber 321 and its position as a late example of this movement's application in the Speedmaster. It bridges earlier designs with subsequent developments, making it a key reference for understanding the model's evolution. Variants primarily involve minor dial and hand differences that occurred during its production run.

The Omega Speedmaster reference 105.012-65 represents a significant iteration within the Speedmaster lineage, being among the early professional models. This reference is distinguished by its asymmetrical case design, which was introduced to provide additional protection for the crown and pushers. It succeeded earlier symmetrical case designs and established a visual language that would become characteristic of many subsequent Speedmaster Professional models. This specific reference was produced during a pivotal period for the model line.

This Speedmaster features a stainless steel case, typically measuring 42mm in diameter. It houses the manual-winding Omega Caliber 321, a column-wheel chronograph movement known for its robust construction and precision. The crystal protecting the dial is made of Hesalite, a material chosen for its shatter-resistant properties. The movement provides a power reserve of approximately 44 hours, ensuring reliable operation over an extended period.

For collectors, the 105.012-65 is notable as one of the last references to utilize the Caliber 321 before the transition to the Caliber 861. Its production year, 1965, places it firmly within the era that established the Speedmaster's enduring appeal. The combination of the asymmetrical case and the Caliber 321 makes this reference particularly sought after, representing a key transitional model in the Speedmaster's development.

The Speedmaster reference 145.012-67 represents a significant iteration within the broader Speedmaster professional line. This particular reference is distinguished by its specific production period and the characteristics associated with watches from that era, including the application of its dial furniture and bezel configuration. It is a key reference for collectors focusing on the evolution of the Speedmaster's design and technical specifications during the late 1960s, preceding later design changes. It is recognized for its robust construction and adherence to the established Speedmaster aesthetic.

This reference features a stainless steel case housing a manual-winding mechanical movement. The case design incorporates the characteristic twisted lugs, a hallmark of Speedmaster Professional models from this period. The watch is fitted with a Hesalite crystal, consistent with its intended use and historical context. The movement within is a column-wheel chronograph, known for its reliability and serviceability, offering a practical power reserve for daily wear.

For collectors, the 145.012-67 is notable as one of the last Speedmaster references to utilize the column-wheel chronograph caliber before the transition to a cam-actuated chronograph in subsequent models. Its appeal lies in its historical placement and the specific details of its production, which differentiate it from earlier and later references. Variants within this reference typically pertain to minor dial and bezel nuances that developed during its production run, making specific examples of interest to those seeking particular configurations.
