The deep green dial, often nicknamed the “Golf Dial,” features a classic tri-compax layout with contrasting subdials, giving the watch a subtle reverse panda aesthetic. Luminous hands and hour markers provide strong legibility, while the stainless steel tachymeter bezel reinforces the Speedmaster’s racing heritage. Its versatile 39mm case makes it extremely wearable while still delivering strong wrist presence.

This movement is known for its durability and ease of service, making it a solid everyday chronograph option. This particular example is accompanied by its original card dated 1999, adding an extra layer of collectibility and provenance to an already uncommon Speedmaster reference.
