Offered in this auction by Second Vintage This is an exceptional example of the Omega Constellation, representing the pinnacle of Omega's luxury and precision manufacturing from the start of the 1970s. Known for its distinctive "C-shape" derived case design and integrated bracelet, this Reference 168.045 offers a robust yet elegant profile that sits beautifully on the wrist. With its chronometer-certified movement and sophisticated vertical brushed dial, this timepiece is a testament to the golden era of Swiss watchmaking, combining arguably one of the best automatic movements Omega ever produced with a design that remains timelessly stylish. Brand: Omega Model: Constellation Chronometer Reference Number: 168.045 Serial Number: 31218017 Movement: Automatic Caliber 751 Dial: Silver vertical brushed Case Size: 36 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1970 Condition: Stunning vintage condition. The watch presents with sharp factory lines and a remarkably clean dial, with timegrapher results between +10 and +14s/day which indicates healthy movement. Dial and Hands The dial features a sophisticated silver finish with a vertical brushed texture that catches the light beautifully, often referred to by collectors as a silky or linen-style finish. It is adorned with applied baton hour markers featuring black inserts for contrast, matched by the original stick hands. The day and date aperture is positioned at 3 o'clock, framed in metal. The text is crisp, featuring the applied Omega logo and the script "Constellation" and "Automatic" at the top, with the "Officially Certified Chronometer" designation at the bottom. The dial is signed "T Swiss Made T" below the 6 o'clock marker, and the overall preservation of the dial face is exceptional with no visible spotting or damage. Case and Crystal The stainless steel case measures 36mm and features the robust integrated lug design characteristic of this reference. The case architecture remains very sharp, retaining its original brushed finishing on the top surfaces and polished chamfers along the sides, showing only minimal signs of gentle use. A defining feature is the intricate fluted bezel which adds a layer of dressy elegance to the sporty steel case. The winding crown is original and signed with the Omega logo. The screw-down caseback features the iconic Constellation Observatory medallion in high relief, surrounded by the eight stars, all of which remain crisp and unpolished. Movement Powering this timepiece is the highly regarded Omega Caliber 751, a copper-colored automatic movement that is chronometer certified. The movement is visibly clean and well-preserved. The rotor is engraved with "Adjusted Five (5) Positions and Temperature" and "Twenty-Four 24 Jewels," highlighting the high-grade technical specifications of this caliber. The movement bears the serial number 31218017. It is currently running within vintage tolerances, with a timegrapher reading of +10 to +14 seconds per day, which indicates healthy movement. Strap The watch is fitted with its original integrated stainless steel brick-link bracelet, reference 1155/146. The bracelet is in excellent condition with minimal stretch, matching the finish of the case perfectly. The folding clasp is signed with the raised Omega logo on the outside and stamped with the correct reference numbers on the inside blades. The bracelet will fit a wrist size of approximately 18.5cm. Condition This timepiece is in stunning vintage condition. It appears to have been worn sparingly and with great care over the last five decades. The dial is nearly flawless, and the case retains its architectural integrity with sharp edges and clearly defined finishes. It is a collector-grade example that requires no immediate attention. Dimensions The case diameter is 36mm excluding the crown, offering a classic fit that wears slightly larger due to the integrated bracelet design and tonneau case shape. Remarks The Reference 168.045 is often sought after for its successful integration of a sporty steel chassis with the elegance of a fluted bezel and a high-beat chronometer movement. It represents a specific moment in design history where the integrated bracelet sports watch began to dominate the luxury market. Finding an example with such a clean dial and a sharp, unpolished case appearance is becoming increasingly difficult. This is a versatile vintage watch that is equally suited for daily wear or as a highlight in a curated collection. History The Omega Constellation line was introduced in 1952 as the brand's flagship model, designated to showcase their highest achievements in precision and design. The Observatory medallion on the caseback symbolizes Omega's record-breaking history in observatory chronometer trials. By the late 1960s and early 1970s, the design language evolved to incorporate the "C-Shape" aesthetics influenced by legendary designer Gerald Genta, eventually leading to integrated bracelet models like this one. These watches from the 1970s are celebrated today for their robust build quality and the excellence of the 700-series movements.
