The New Breguet Marine Tourbillon 5577 now Sports a Thinner, Sleeker Look

Most watch enthusiasts are unlikely to describe Breguet as a sports watch manufacturer, but it's an undeniable fact that Type XX is a pilot’s chronograph that saw two new models recently. The other significant line-up that needs to be mentioned in this regard is the Marine, which was introduced when Abraham-Louis Breguet was appointed chronometer maker for the Royal Navy. After releasing variants of Hora Mundi 5557, Chronographe 5527, and Alarme Musicale, Breguet has now unveiled two new sport-y Marine Tourbillons in 18 ct rose gold (Ref. 5577BR/G2/5WV) and platinum (Ref. 5577PT/Y2/9WV).

Invented by the brand’s founder, A.L. Breguet, in 1801, the tourbillon addressed the challenge posed by Earth’s gravity on the regularity of watch movements. Designed to counter the variations in rate due to gravitational pull, the tourbillon achieved this by placing the entire escapement within a mobile carriage, completing one rotation every minute. This ensured that any errors in timekeeping were consistently negated, emphasising the brilliance of Breguet’s innovation.

Here, we are looking at one of the sleekest editions of the Breguet Marine. First, while retaining the signature and rather complex design of the collection, the case has been streamlined to achieve a diameter of 42.5 mm. Available in 18 ct pink gold or platinum, this complex watch remains devoted to yachting with a screw-down crown, protected by lateral guards at 3 o’clock.

The dial of the just-launched Marine Tourbillon 5577 follows the same principle as the previous models. No more wave-like guilloché pattern here but a robust dial that shows a classic sunray-brushed pattern; depending on the case, it’ll be slate-grey for the rose gold version and navy blue for the platinum model. While the tourbillon is located at 5 o’clock with its cage rotating in 60 seconds, the chapter ring remains off-centred for a view of the movement, with Roman hour markers sporting open-tipped gold Breguet hands, which are luminescent. The crown and the crown guards also come in the same material as the case.

Inside the case lies the in-house, self-winding Calibre 581, an ultra-thin movement that is just 3 mm thick and comprises 330 components. This thinness is achieved through the use of a peripheral oscillating weight that is placed on the outer periphery of the caseback, offering a power reserve of 80 hours.

Turning the watch over showcases the sapphire caseback in platinum or 18 ct rose gold, a barrel drum that bears a compass rose, and a straight ribbed motif. The new Tourbillon Marine is available with a brown rubber or an alligator leather strap. You can also opt for a rose gold bracelet for the rose gold model and a midnight blue rubber or alligator leather strap or a platinum bracelet for the platinum model.
