The 1990s Seamaster 120 is a classic, 36mm sports watch that hails from Omega's 1990s resurgence. A highly wearable piece that echoes the Diver 300m of that era, they are powered by the 1109 and 1120 calibres.
Our sapphire exhibition caseback allows you to admire the fine Geneva Stripes and custom finishing of these reliable movements. With our expertise engineering exhibition casebacks for vintage and modern luxury timepieces, we've developed a design that preserves the 120m water resistance rating while reducing the watch thickness by approximately 0.5mm.
This caseback seamlessly blends heritage and contemporary style, offering a tangible connection to the craftsmanship that powers your piece of Swiss watchmaking history.
How it's Made:
Our caseback is meticulously crafted with attention to detail. It comprises an outer ring made from high-quality 316L stainless steel, precision-machined to exact specifications. The slots designed for the opener tool undergo a thorough sandblasting process to eliminate any machining marks, providing a clean and refined look. A brushed finish is then applied, which creates a striking contrast with the polished bevel edge.
We securely fit the stainless steel ring with a scratch-resistant sapphire crystal. To enhance clarity for viewing and capturing photographs of your watch movement, we apply a colorless, multi-layer AR coating to the internal face of the crystal. This coating ensures that you enjoy a clear and unobstructed view of the inner workings of your timepiece.
