The elegant OMEGA Seamaster 43.5mm is a respectful tribute to OMEGA's legacy in dive watches. This specific model, equipped with a robust scratch-resistant sapphire crystal, showcases a meticulously polished black ceramic dial adorned with Arabic numerals and thoughtfully positioned at the 3 o'clock mark, a date window. Resting atop the 43.5mm stainless steel case is a black ceramic bezel, featuring an orange rubber inlay. The diving scale of this bezel is meticulously crafted with Liquid metal. This timepiece impressively maintains water resistance up to 600 meters and is equipped with a helium-escape valve for enhanced functionality. The OMEGA Master Chronometer calibre 8900, housed at the core of this timepiece, can be viewed through the transparent case back.
