About this reference
Omega lists 311.30.44.50.01.001 as a steel Speedmaster Moonwatch chronograph on a steel bracelet, with a black dial under a tachymeter bezel. One photo shows the watch from the front and one in the hand, so you can look over the dial layout before you order.
Movement and size
Speedmaster chronographs come in more than one size and with more than one kind of movement. If the case size, the winding or a date window matters to you, message the team before you order and they will check the watch you would receive. Our size guide puts the 42 mm Speedmasters with wrists of 16.5 to 19 cm and the 44.25 mm models with wrists over 19 cm. For a reference that Omega makes at 42 mm, see the Moonwatch Professional 310.30.42.50.04.001; the Panda 311.32.40.30.02.001 is about 40 mm.
Water and care
Splashes, showers and swims are all fine. Magnets can disturb the timing, so don’t leave it on a speaker or next to a phone case with a magnetic clasp.
Ordering
The team films your watch and sends the clip with a set of photos, and it ships once you are happy with them. Returns within 14 days are covered on the returns page, and the Omega box and papers are a separate listing.
