The new generation of Constellation Observatory watches integrates these vintage elements into a modern 39.4mm case, crafted from materials ranging from stainless steel to yellow gold and platinum. Thanks to the use of a double-sided box-shaped sapphire crystal, the mid-case appears relatively slim (with a total thickness of 12.23mm), resulting in an elegant presence on the wrist. The case length is also kept quite restrained, with a lug-to-lug distance of 47.2mm. As a tribute to the past, this timepiece revives the series' classic and distinctive aesthetic, featuring highly recognizable "horn" lugs. Another element paying homage to history is the return of the "pie-pan" dial; the outer ring of the dial is adorned with *guilloché* patterns (with the exception of one specific version, the stainless steel models feature stamped patterns). The three-dimensional "kite-shaped" indices complement the similarly shaped hands perfectly. Omega’s logo and the Constellation star emblem are rendered as three-dimensional applied elements, while inscriptions such as "Observatory," "Co-Axial," and "Master Chronometer" are presented via transfer printing,Omega Seamaster replica watches.
The series launches with several distinct versions: the stainless steel models utilize Omega’s proprietary O-MEGASTEEL alloy and are available with a silvery opaline dial (featuring gold indices and hands), blue or green PVD-coated dials, or a polished black ceramic dial; all stainless steel versions are paired with a glossy alligator leather strap. Next are the various precious metal versions, encompassing all of Omega’s patented gold alloys: the Moonshine™ Gold version features a matching dial and offers a choice between a leather strap or a mesh bracelet; the Sedna™ Gold and Canopus™ Gold versions also feature matching dials and come fitted with leather straps. Finally, there is a platinum version—marking the first time Omega has assembled all four of its patented precious metal alloys within a single collection.
Perhaps the most surprising aspect is that this timepiece—dubbed the "Observatory"—is, in fact, a simple two-hand watch devoid of a central seconds hand. Typically, observatory-grade watches (particularly those intended for observatory chronometer competitions) are equipped with a seconds hand to facilitate precise timekeeping. Moreover, until now, the presence of a seconds hand has historically been a prerequisite for a watch to obtain official chronometer certification. However, upon closer reflection, why is it that the precision of a two-hand watch cannot be certified? We will revisit this point a little later. Through the sapphire crystal case back, one can admire Omega’s in-house automatic movement. This new collection is powered by two new calibers—albeit ones based on the classic 89xx architecture—which feature a skeletonized oscillating weight and are adorned with the Constellation Observatory medallion
