The Omega Speedmaster 40 Mark 4 Automatic Chronograph, reference 3520.50.00, is an iconic timepiece that blends elegance, performance, and precision while preserving the sporty DNA that defines the Speedmaster collection. This model from 1999 is a high-precision watch, highly appreciated by fans of technical and sporty chronographs.

Featuring a stainless steel case with a 38mm diameter (40mm including crown and pushers), this Speedmaster offers a bold presence on the wrist while remaining comfortable thanks to its well-balanced proportions. Its design is reminiscent of the iconic models from the range, with a fixed tachymeter bezel, robust styling, and a highly detailed dial. The black dial with white markings ensures excellent legibility, with luminous indexes and hands that provide optimal readability in low-light conditions.

One of the standout features of this Omega Speedmaster is its Omega C-1151 calibre, a high-precision automatic movement based on the legendary Valjoux 7751. This movement incorporates 25 jewels and offers a power reserve of approximately 44 hours, ensuring reliable and long-lasting accuracy. The watch includes advanced functions, notably a three-register chronograph (including a multifunction 24-hour sub-dial), as well as a day, month, and date complication, adding practicality and richness to its features.

As for the bracelet, this Speedmaster Mark 4 is equipped with a stainless steel bracelet that perfectly complements the case, providing a solid and comfortable fit. The folding clasp ensures secure wearing while allowing for quick and convenient adjustment. This type of bracelet enhances the sporty and timeless spirit of the watch, while blending seamlessly with its bold design.

Compared to other Speedmaster models, this automatic version with triple calendar stands out for its more practical and functional design for everyday wear, while preserving the soul of Omega’s iconic chronographs. Unlike the legendary Speedmaster Professional Moonwatch with its manual-wind movement, this version features an automatic calibre, making it more user-friendly for daily use. With its feature-rich dial and useful complications, it’s an ideal timepiece for enthusiasts seeking a versatile and iconic sports watch.

This Omega Speedmaster 40 Mark 4, reference 3520.50.00 from 1999, is offered by Mostra with its original Omega box and a Mostra certificate of authenticity, ensuring its authenticity and excellent condition.
