Experience the craft of Breitling in the Montbrillant (ref. A4137012/G789/223A), a distinctive model that balances proportion, precision, and presence. On the wrist, the case feels purposeful: crafted in stainless steel and measuring 38 mm in diameter, with a thickness of 13 mm, defined by a round silhouette, paired with a sliderule bezel. The caseback is closed, and the crystal is sapphire, delivering water resistance to 3000 meters. Visually, the face is where character emerges: a white tone, framed by stick / dot hour markers, and alpha hands. Mechanically, the watch prioritizes accuracy: the Caliber 41 caliber. Initial production year: 2019. The silhouette offers presence without excess, lending confidence in a range of situations. Finishing showcases disciplined attention to detail across facets, edges, and surfaces. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
