EPOS 3440 Big Moon – a Swiss watch that brings the beauty of the night sky to your wrist

Some horological complications are designed solely to tell time. Others are capable of evoking emotion. The EPOS 3440 Big Moon belongs to the latter category. It is an extraordinary Swiss mechanical watch inspired by one of the most beautiful phenomena observed for thousands of years – the night sky and the changing phases of the Moon.

At the heart of the model is the proprietary complication developed by EPOS, Big Moon. Unlike classic moon phase indicators, a large, three-dimensional silver moon becomes the central element of the dial. Surrounded by shining stars and a deep background reminiscent of a starry sky, it creates a composition that captivates both by day and after dark. This is not just a function – it is a true work of horological art.

The watch movement is based on the renowned Swiss Sellita SW300 / ETA 2892 calibre, which has been enhanced with EPOS's own module responsible for displaying the large moon phase and decentralized day and month indicators. Thanks to the transparent case back, you can admire the precisely finished movement with perlage decorations, which is a testament to the craftsmanship of Swiss watchmakers.

The 42 mm diameter 316L stainless steel case is equipped with scratch-resistant sapphire crystal on both sides. Its slim design, elegant proportions, and perfect finish make the EPOS 3440 Big Moon look equally stunning with a suit or in everyday outfits. This is a watch for those who appreciate timeless elegance but also expect exceptional technical solutions.

For years, EPOS has proven that traditional Swiss watchmaking can surprise with new ideas. The 3440 Big Moon model is a perfect example – it combines classic mechanics with a poetic interpretation of the night sky. It is a timepiece that not only tells the time but also serves as a daily reminder of the constant rhythm of nature and the beauty of the universe.
