OMEGA Constellation Bracelet ST 1448 / 431: Classic Stainless Steel Elegance for the Mid-Size Manhattan

The OMEGA Constellation ST 1448 / 431 bracelet is a hallmark of timeless Swiss design, crafted specifically for mid-size Constellation Manhattan models produced in the late 1980s and early 1990s. Made entirely from stainless steel, this bracelet features OMEGA’s signature mono-rang (single horizontal row) layout, perfectly integrated with the case to deliver a seamless, refined aesthetic.

As one of the earliest modern Constellation bracelet designs, the ST 1448 / 431 offers understated sophistication, enduring build quality, and a wrist-hugging fit—making it a go-to choice for collectors, restorers, and wearers who appreciate minimalist design with strong heritage.

Reference Breakdown

• ST: The “ST” prefix indicates stainless steel construction. This bracelet is crafted entirely from high-grade brushed steel, making it durable, corrosion-resistant, and suited for daily wear.

• 1448: This design number refers to one of the most recognizable bracelet styles from the Constellation Manhattan line. The mono-rang format consists of flat, articulated horizontal links arranged in a single row. The links are gently curved for a close fit on the wrist, while the brushing provides a soft, matte finish that enhances its visual appeal.

• 431: The end link reference, precisely manufactured for 19mm integrated-lug Constellation cases. These solid end links are not interchangeable or universal; they are uniquely shaped to deliver a flush, gapless connection with the mid-size Manhattan case, preserving the collection’s integrated aesthetic.

Key Features

• Material: High-quality brushed stainless steel with polished bevels for subtle contrast and longevity
