Short answer
An Omega Speedmaster T copy is a tribute watch built to resemble a Speedmaster Professional with a "T SWISS MADE T" dial. That marking sat on Omega dials that used tritium paint for the hour markers and hands, a practice Omega ran from the mid 1960s until tritium was phased out in the late 1990s. A copy of a T-dial reference repeats the dial text, the aged lume tone, the 42 mm case profile, and the handset. It is not a genuine Omega and it must never be sold or described as one.

What the T marking tells you
The letters on either side of "SWISS MADE" at the bottom of the dial flag the luminous material. "T" means tritium, which fades to a warm cream or pumpkin tone with age and stops glowing once it is spent. Dials marked only "SWISS MADE" came later, after Super-LumiNova replaced tritium. The Speedmaster references people most often copy are the 145.022 and 3570.50 families, plus the moonwatch 3570.50.00 layout with its three registers at 3, 6, and 9.
Parts that separate a solid copy from a poor one
- Dial printing: the words "OMEGA" and "Speedmaster" should sit level, with even letter spacing and a clean line under the logo.
- Lume tone: markers and hands should match each other, not one cream and one orange.
- Bezel insert: font weight, dot placement, and the dot over 90 all differ between good and cheap inserts.
- Case: 42 mm across, 20 mm lug width, with a step between the bezel and the mid case.
- Crystal: domed hesalite on vintage tributes, flat sapphire on modern ones.
- Movement: a manual chronograph looks and feels different from a quartz copy when you wind it.
How to inspect a T copy in person
- Measure the case across the widest point of the mid case, not the bezel, and confirm it reads close to 42 mm.
- Place a loupe on the dial text and check that the letters are not smudged or double printed.
- Compare the lume color on the hour markers against the hands under daylight, since mismatched tint is the most common flaw.
- Study the bezel insert for a sharp dot over 90 and even numerals.
- Wind the crown through twenty turns and listen for a rough or gritty feel.
- Start the chronograph, let it run for ten minutes, and stop it to see whether the seconds hand snaps back to zero.
- Turn the watch over and read the caseback engraving for depth and clean edges.
- Weigh the watch on a kitchen scale, because a stainless copy of this size usually lands between 120 and 145 grams on a bracelet.
- Ask for a photo of the movement if the back is transparent, and identify the calibre before you pay.
Movements you will meet
Most T copies run one of three movements. The Seagull ST19 is a manual wind column wheel chronograph and the closest feel to a vintage Speedmaster. Clones of the Lemania 1873 appear in higher priced tributes and offer a smoother pusher action. Quartz versions are thinner, lighter, and cheaper, but the pushers feel dead and the seconds hand ticks instead of sweeping.

Lume and aging expectations
Factory tritium aged over decades, so its color varies from watch to watch. Copies get their tint from paint mixed at the bench. Expect the tone to stay fixed, and expect no glow after dark. If a seller claims the copy has genuine tritium, that claim is false.

Before you buy
Set a budget, decide between manual and quartz, and ask for clear photos of the dial, caseback, and movement. Keep the receipt. Wear the watch as a tribute piece and disclose what it is if anyone asks. Passing a copy off as a genuine Omega is fraud in most markets, including the United States.
