Measuring 20mm at the lugs and 18mm at the buckle, it was equipped with a rounded brushed clasp (with safety pushers) and engraved with the same mentions as found at 12 o’clock on the dial (logo, brand, Speedmaster, Professional). 3750.50 was equipped with a brushed band with polished inter-links – reference 1998/849. The printing at 12 is showing a triangular arrangement, with the wide Ω logo on top, followed by the name of the brand, the “Speedmaster” mention with a short and wide S and finally, a larger “Professional” mention with tall font.Īs for the bracelet (not shown here), the ref. The “flat” mention isn’t entirely true though, since the dial has an angled periphery with long markers for the seconds/minutes, short luminous hour markers (they don’t cross into the minuterie) and a chronograph track with 5 divisions per second – which doesn’t make sense with a 3Hz movement… The hour and minute hands are straight batons painted in white, while the second hand has a so-called diamond tip (which is quite small and rather close from the centre of the dial) and a flat counterweight, which appeared in 1968. The dial is a so-called flat dial, in opposition to the step dials that were found until 1975 on vintage Speedies.
Also available with a “sapphire sandwich” construction, the classic model features a synthetic Hesalite crystal (with the small Ω logo in the centre).Īs for the dial, the pre-2021 Speedmaster Moonwatch Professional has a matte black, slightly grained texture with recessed sub-counters featuring a snailed pattern in the centre, but not on their flange.
The 42mm stainless steel case mostly features brushed surfaces, with a polished bevel running on the side. Except for the change from tritium to Super-LumiNova, a new presentation box and small updates on the bracelet, nothing has changed in well over 20 years of production. The Speedmaster as we know it today, with the reference 3570.50, has been in the collection since 1996 when Omega launched the calibre 1861, an evolution of the 861 that appeared in 1968. This shape remains practically unchanged since 1964 and it is what we still find in the pre-2021 Speedmaster Moonwatch Professional. The “Professional” mention appears together with the implementation of the new asymmetrical case, with its lyre-type twisted lugs and protection for the crown and pushers – with a diameter that coincidentally grew from 39.7mm to 42mm, albeit with a slightly smaller lug-to-lug measurement. So first of all, let’s start by exploring the older, pre-2021 reference 311.30.42.30.01.005 (also known as 3570.50 with the older nomenclature), with its 42mm asymmetrical steel case, Hesalite crystal, hand-wound calibre 1861 – and a fair amount of dust and scratches, being my personal, used and abused watch (which I bought new in 2012).Īlthough it was born in 1957, under the reference CK2915, the Speedmaster as we know it today, the so-called “Professional,” came on the market in 1964 under the reference ST 105.012. Because the new reference looks almost identical at first sight, but since almost everything is new, even for us, it was important to take the time to look at an older Speedmaster Moonwatch Professional in details. The Speedmaster Moonwatch Professional… until nowīefore we look at the new Speedmaster Moonwatch Professional Master Chronometer, it is important to refresh our memory. Why? Because actually, almost every single element of this Omega Speedmaster Moonwatch Professional Master Chronometer is new… But (thankfully) it still very much looks like a Moonwatch.
#Omega speedmaster moonwatch professional chronograph update#
We covered the launch of the watch a couple of days ago however, such an update needed to be explained once we had the opportunity to see the watch. Clearly, Omega wasn’t allowed to mess with this watch and everything that had to be changed, removed, redesigned or updated had to be carefully weighed. This probably won’t come as a surprise to you but… there’s a new regular production Speedmaster Moonwatch Professional! As far as I can say, this is big news, simply because we’re talking about one of the most iconic and most respected watches ever produced, and a watch that has been in continuous production since 1957.
