Bvlgari Diagono Calibro 303 fashion chronograph watch Fashion

With its signature styling and a well-chosen automatic movement that keeps it ticking, new Bvlgari Diagono Calibro 303 Chronograph looks like a nice choice for a person in search for a sportier kind of a reliable timekeeper that doesn’t try to look like your average run-off-the-mill Omega or Breitling.

Overall Impression

Looking at this new product I can’t help but compare it with Hublot’s successful Bing Bang family. It is a bit strange since this new Bvlgari Diagono Calibro 303 Chronograph wristwatch features a radically different design starting with a solid body and sword-shaped hour and minute hands. However, the feel of this timepiece, its sporty appearance suggest that the Swiss-based branch of the Italian fashion brand clearly tried to reverse engineer Hublot’s secret of success.

Still, however secondary it may feel, it still looks interesting and even fascinating (at least, for a fashion accessory) design that, with certain reservations, can be recommended as a dress watch of choice for a person who isn’t afraid of combining a Ralph Lauren orange polo shirt with a green double-breasted blazer by Sottono.

The new watch is equipped with what Bulgari prefers to market as Caliber BVL 303 automatic movement with a column-wheel chronograph complication. Based on Frederic Piguet 1185 automatic movement that has been here for ages, the movement comprises 303 parts (hence the name Bulgari gave its own version) is thin and is also quite accurate since it was designed to compete with the best of the best in the field: under different names and with different finish, the caliber is used by such established brands as Omega, Blancpain, Vacheron Constantin, and even Breguet.

The mechanism was, by the way, originally developed as a hand-wound engine, but the Swiss Manufacture has soon added a self-winding version that added just over 1.5 mm to the original’s 3.95 mm thickness. With a diameter of 25.6 mm, the FP 1185 is only 5.5mm thick!

Since the movement is visible through a display back, which is covered with a sapphire crystal, it is painstakingly decorated with such traditional techniques as perlage, Satine Soleil, and the signature Cotes de Geneve stripes on the oscillating weight that match the same pattern on the dial.


The case of the time measuring device is made of satin-finished stainless steel and features a fixed 18-karat white gold bezel with the inevitable pair of stamped “BVLGARI” logos and scratch-resistant sapphire crystal with anti-reflection treatment.

Measuring 42 millimeters in diameter and almost 13 millimeters in height, the watch looks relatively small compared to the recent flock of “sporty” chronographs that feature gargantuan proportions and look like you can kill an elephant with it.

Still, it must be noted that, due to the shape of its rather long lugs, the watch tends to take almost all available space on a wrist, so be sure to try it before placing an order in an online shop.


The Bvlgari Diagono Calibro 303 also sports exquisite multi-layer dial with their trademark satine soleil finish, vertical treatments and faceted hand-applied indexes.

The dial features a standard tri-compax layout with a pair of chronograph counter at 3 and 9 o’clock and a subsidiary seconds subdial at 6 o’clock with a small date aperture cut out in its inner part.

To increase the legibility of the piece, the Italian watchmaker has equipped the small seconds indicator with a high-contrast black hand, while the other five hands are gold-plated. The hour and minute hands, as well as the applied hour markers (also gold-plated) feature thin stripes of C1 Superluminova, so night-time legibility also not going to be an issue.

Certainly, a watch to have.

  5. i took delivery of mine about 4 weeks ago….and love it…at the time it was the only one in the country (so i have been told)

    I have this watch. very nice one..

  8. I bought the 303 as a sportwatch but my other watches get little wrist time now. A beautiful watch that is incredible value for the price! Beats a Daytona hands down and to my eye is more attractive than the Royal Oak which shares the same movement.

  9. Hi, Could you tell me how can i know is a calibro 303 is original or not, because someone offers me one and i dont know about watches.

    Thank You very much.
