A Brief History:

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 Tank 165.0025 with Caliber 1012 in excellent condition. The Cal 1012 was extensively used in many constellation models especially the 165.0025 because of its high performance.

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

Its case was 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 excellent condition albeit scratches do remain.

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

The movement was given a good clen-up and oiled on 28 July 2026. The timing shows approximately 6 seconds deviation daily which is well within the 30 second requirements for by brand new modern automatic watch standards.

Equipped with the well revered 1012 movement, it has 23 Jewels and operate at 28,800 BPH. It should be able to operate unhindered until the next servicing thereby giving the owner peace of mind.

The case width and height are approximately 34mm (w/o crown) and 42.5mm respectively. The lug width is 18mm and the bracelet can accommodate wrists up to 17.5cm; hence, this watch is suitable for men and the modern women.

The watch comes with a brand-new Time King brand genuine rosewood leather strap with Omega signed gold buckle.

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!

This is a highly sort-after Omega Tank Cal 1012 165.0025 Automatic Watch; so, be unique and own a 1973 Omega cultish Tank Birthday Watch that is almost impossible to source in such fine condition or purchase it for that special someone instead.
