Fat Cases: Panerai PAM 187 vs. Tudor 7924

The Submariner reference 5510 is a notable example within the early production of the model line, distinguished by its "Big Crown" design. This reference was produced for a very short period, making it one of the rarer variants. It represents a transitional phase in the Submariner's development, bridging earlier designs with later, more standardized configurations. Its aesthetic aligns with the functional tool watch philosophy prevalent at the time of its introduction.

The case of the reference 5510 is constructed from stainless steel, featuring a diameter characteristic of its era. It houses an automatic movement, specifically the Caliber 1530, which provides reliable timekeeping. The crystal protecting the dial is made of acrylic, a common material for watches of this period, contributing to its period-correct appearance. The water resistance rating was a significant feature for the model at its release.

This reference appeals to collectors interested in the foundational period of the Submariner. Its limited production run and specific design elements, particularly the oversized winding crown, contribute to its desirability. The 5510 is considered a key reference for understanding the evolution of the Submariner series, showcasing the design language and technical specifications that preceded subsequent iterations.
