Bulgari focuses on its eight-sided Octo Roma collection for early 2023 as it launches the collection’s first chronograph. In addition, look for three new Bulgari Octo Roma Automatic dial options and four Octo Roma Tourbillon watches, each with its own technical twist.
Octo Roma Chronograph
As an early 2023 focus debut, the new Octo Roma Chronograph introduces a new Bulgari movement, Caliber BVL 399, visible through the watch’s clear sapphire back.
Two models are included in the debut, one with a black dial and one in blue. Both feature an eye-catching Clous de Paris, or hobnail, pattern that appears as small pyramids across the dial, here broken only by the three sunburst-pattern chronograph subdials. 
Bulgari has been especially careful designing the pushers, which are nicely integrated into the 42mm by 12.4mm steel case. The pushers are only slightly visible, seemingly flowing from the angled lugs directly to the crown protector. 
The new Bulgari Octo Roma Chronograph also features a screw-in steel crown with a ceramic insert, is water-resistant to 100 meters and offersSuperLumiNova-filled metallic hands, indexes and numerals.
Bulgari attaches the watch to the wrist with a polished and satin-brushed stainless-steel bracelet with a folding clasp and includes an easily interchangeable rubber strap with each watch.
Price: 9,900 euros.
Octo Roma Automatic
Sporting the same fetching Clous de Paris dial treatment as the new chronograph, the three new automatic models each offer a three-dimensional dial option to the Roma Automatic collection. Differing ambient light levels will subtly alter the character of the dial, though the large 12 and 6 and the long hour markers allow time to be read quickly at any angle. The hands, hour markers and Arabic numerals are enhanced with SuperLumiNova.
Bulgari offers three colors with the new dial pattern: blue, anthracite and white. 
This 41mm by 9.1mm steel watch with three hands and date is powered by the existing in-house Caliber BVL 191 movement decorated with Côtes de Genève motif, visible through the clear sapphire back.
Bulgari equips both the Octo Roma Automatic and the Octo Roma Chronograph with a tool-free interchangeable wristband system. Each watch is also water-resistant to a depth of 100 meters.
Price: 7,900 euros.
Four Octo Roma Tourbillon Watches
Two of the Tourbillon models, the Octo Roma Precious Naturalia (165,000 euros) and Precious Tourbillon Lumière (190,000 euros) both feature minerals within their cases or dials.
The former includes polished tiger eye on its caliber, mainplate and indexes while then latter glows with diamonds set across a 38mm rose gold case.
Two Bulgari Octo Roma tourbillon debuts are especially contemporary. One, the 44mm Octo Roma Papillon Tourbillon (130,000 euros) is a black DLC titanium-cased, jumping hour model named in reference to the Daniel Roth precursors of yore. Sporting a very rare central tourbillon, the watch shows the hour through a fixed window at noon, while the minutes are displayed on a semicircle graduated from 0 to 60 and alternately traversed by two diamond-shaped hands.
The second contemporary model is an Octo Roma Striking Tourbillon Sapphire (85,000 euros) that revives an earlier flying tourbillon chiming model, but with a newly refined black DLC titanium and sapphire case. We’ll have more information and images of these two new models in future posts.

Grand Seiko tests its Tentagraph movement for twenty days with a strict precision goal of +5 to -3 seconds per day.
In addition, Grand Seiko builds a vertical clutch and a column wheel into the movement, both of which enhance accuracy and chronograph control.
The sapphire crystal case back reveals a beautifully finished Caliber 9R01 movement’s one-piece bridge, designed in the image of Mt. Fuji. Price: $260,000.
Each artfully sets diamonds into the bezel and/or adjacent upper and lower case (on Pave models) of the existing square series cased in titanium and Hublot’s own King Gold alloy.
Titanium is naturally corrosion resistant as a case material, but Delma also enhances the watch with a ceramic bezel, which offers a new level of scratch resistance to the watch.
