Introducing Sinn Diving Watches (ref. 1011.021), a refined timepiece that blends thoughtful design with reliable performance. A study in proportion and durability: crafted in stainless steel and measuring 44 mm in diameter, with a thickness of 18 mm, defined by a round silhouette, paired with a rotating, 0-60 (dive) bezel, protected by pvd coating. The caseback is closed, and the crystal is sapphire, delivering water resistance to 100000 meters. The dial composition is deliberate and legible: a green tone, framed by stick / dot hour markers, and sword hands. Beneath the caseback lies dependable performance: the SZ02 caliber. Issued as a limited edition, appealing to focused collectors. First released in 2015. Comfort and balance define the wearing experience, making it an easy daily companion. Subtle transitions between textures elevate the overall impression. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
