THE HISTORICAL RETROSPECT

The Bulgari Diagono series was introduced in 1994, taking inspiration from the Greek word "agon," meaning competition. The series began with the Scuba model, characterized by its sporty yet sophisticated design. The Diagono series has always been geared toward individuals with an active lifestyle, blending robust construction with elegant aesthetics​. Over the years, Bulgari has continued to innovate within this line, incorporating advanced materials and in-house calibers to enhance the performance and appeal of their timepieces. The Diagono Professional GMT, Ref. GMT 40 G, produced in the 2000s, stands as a testament to Bulgari's commitment to blending tradition with modernity, making it a cherished piece among watch collectors​.

THE DESIGN DETAILS

The 40mm diameter solid three-body case, screwed straight lugs, and bidirectional rotating brushed bezel with a GMT 24-hour time graduation are crafted from solid 18K yellow gold, offering both durability and a luxurious appearance. The case features a polished and brushed finish, enhancing its visual appeal. The robust construction and the secret-down crown ensure water resistance up to 100 meters, making it suitable for everyday wear and light water activities. The matte brushed finish of the case helps in aging gracefully, developing a unique patina over time​.

The black matte dial provides a striking contrast to the gold elements of the watch, adding depth and character. The dial design ensures readability with its luminous hands and bold, applied hour markers. The subsidiary date dial at 6 o'clock enhances the watch's practicality. The outer rim of the dial features a raised white 24-hour indication on a blue and red background.

The pushers at 2 and 4 o'clock allow for easy and intuitive hour adjustments in 1-hour increments after setting the GMT hand (the red arrow hand) to the desired second time zone using the crown. The pusher at 8 o'clock facilitates quick date correction, ensuring the watch remains accurate and user-friendly while traveling.

The hands and hour markers are crafted with meticulous attention to detail. The polished yellow gold-toned hands are filled with luminous material, ensuring visibility even in low-light conditions. The hour markers are bold, applied indices, with an Arabic numeral at 12 o'clock, ensuring clarity and elegance​.

THE MOVEMENT & CRAFTMANSHIP

The Bulgari Caliber 312 is an automatic movement based on the renowned ETA/Valjoux 7750, further refined by La Joux-Perret. This movement is known for its reliability and precision, operating at an oscillation frequency of 28,800 vibrations per hour (4 Hz). It features 21 jewels, which reduce friction and wear, enhancing the movement's longevity. The movement also includes a monometallic Glucydur balance and a customized rotor with snailing decoration​.

The GMT function is designed for travelers, allowing them to keep track of two time zones simultaneously. The additional hour hand, indicated by a red arrow, completes a full revolution every 24 hours and points to the corresponding 24-hour scale on the bezel.
