The Omega Constellation has a very interesting history that needs to be told.

The year 1933, at the Kew-Teddington Observatory, Omega set world records for precision in every category and repeated this achievement in 1936. A total of 8 records were accomplished between 1933 and 1952 (2 chronometer records and 6 first-place awards) thereby giving this timepiece its name Constellation with the 8 stars, and an observatory on the back case - very symbolic indeed.

The Constellation made its debut in 1952 to succeed the Omega Centenary, and was initially equipped with the Cal 354 AKA “bumper automatic” that does not fully rotate a full circle but instead, it "bumps" off springs at either end of its pendulum arc hence a back and forth movement, giving it a rather distinctive feel on the wrist – you can actually feel the rotor "bumping." Invented by English watchmaker John Harwood in 1923, this "bumper automatic" may be considered the world's first "kinetic" energy system.

Omega introduced the 500 series of movements for the Constellation in 1958 that uses a full rotor system used in modern watchmaking. The dial that accompanied this movement was affectionately known as the "Pie-Pan" - one of the most gorgeous and timeless dials one will ever come across - it is simply mesmerizing.

Here we have an Omega Constellation 168.0065 with Caliber 1011 in stunning condition. The Cal 1011 was extensively used in many constellation models especially the 168.0065 and various Pie Pan series because of its high performance.

It has a beautiful silvery-white dial, date window, 3D white gold baton Indices with dauphine hands that are found well preserved after a deep cleaning.

Its traditional dog legged lug case was cleaned via carefully cleaned and polished as best as possible without compromising its shape and lines albeit a few miniscule scratches that are barely noticeable to the naked eye. The crystal was replaced and is now in mint condition.

The crown is located at the traditional 3H position and is easily accessible. The date and time comes with quickset capabilities by uncorking the crown to the first and second levels and adjust the date and hands respectively.

The movement INCLUDING THE MAINSPRING was carefully stripped, meticulously cleaned, oiled, re-assembled and a calibration was conducted on 2 September 2025. In short, it was given a full overhaul and not a general servicing, and should be able to operate unhindered until the next servicing thereby providing the owner peace of mind.

Equipped with the well revered 1001 movement, it has 23 Jewels and operate at 28,800 BPH. The time-grapher shows superb readings of 0 seconds and amplitude of 187 with a super straight line! Such readings are truly exceptional even by brand new modern automatic watch standards whereby the accepted tolerance is -20 to +40 seconds a day! This is a testament to the quality, excellent power reserve and longevity for such a vintage timepiece, the meticulous care provided over the years, and of course the painstaking expert calibration conducted.

The case width and height are approximately 34mm (w/o crown) and 42.5mm respectively. The lug width is 18mm and the leather strap can accommodate wrists up to 20.0cm; hence, this watch is suitable for men and the modern women.

The bracelet was also given a thorough ultrasonic cleaning and buffed. A brand new hi-quality Crepha brand genuine leather strap with silver buckle also accompanies this watch as part of the deal.

Due to its age, this timepiece has not been water-resistant tested.

The pictures provided shows the watch in superb condition, and the movement within squeaky clean and well maintained. It has also been demagnetised to improve parts reliability, minimise wear + tear, and improve accuracy. The only drawback is the lack of documentation and original box. An aftermarket box or purposeful carrying pouch will be provided instead.

Bear in mind that this watch has seen many of the previous owners’ ups and downs in life, and should be cherished and preserved for the next generation to savour such engineering beauty.

Yes, there are many other same / similar models in the market, BUT none as beautifully aged and as well maintained as what you see here. Hence, it is a no-brainer that this one-of-a-kind watch will make an extremely beautiful birthday present for that special someone born in 1973! Another no-brainer is the fact that the value of this watch will appreciate over time.

Do also bear in mind that it will cost between S$ 400.00 to S$ 600.00 for a proper overhaul and S$ 150.00 to calibrate an Omega timepiece; and S$ 80.00 to clean and polish the watch case and bracelet - these costs do not apply when purchasing this timepiece. So, if anyone was to sell such a timepiece at a low price yet claim that it has been serviced, one has to ask what kind of servicing was conducted, if any.

This is a highly sort-after Omega Constellation Chronometer Cal 1011 168.0065 Automatic Watch; so, be unique and own a watch that is almost impossible to source.

This is a must-have for the Omega die-hard fan, and in fact, any serious watch collector for that matter!
