The Omega Speedmaster Moonwatch Professional, reference 3861, represents a significant evolution within the Speedmaster collection.

It is positioned as a contemporary iteration of a well-known chronograph, appealing to collectors who appreciate both heritage design and updated mechanical performance.

This Speedmaster Moonwatch Professional features a 42 mm case, with a thickness of 13.18 mm. The case houses the Omega Co-Axial Master Chronometer Calibre 3861, a manual-winding movement. The crystal protecting the dial is available in hesalite or sapphire, depending on the specific sub-reference. The movement provides a power reserve of 50 hours, ensuring reliable operation over an extended period.
The reference 3861 appeals to collectors seeking a Speedmaster with enhanced precision and anti-magnetic properties, certified as a Master Chronometer. Its availability in materials such as stainless steel and Moonshine™ gold allows for diverse collecting strategies. The consistent case dimensions and movement across these variants underscore a unified design approach, while material choices offer distinct visual and tactile experiences.
The relevant ones for me are: - the slim chrono counter - the movement - the bracelet What I do not care about: - dot over 90: pfff I could not care less about this - caseback: yuck
Nevertheless i think Omega did quite a job going this thin line between keeping the heritage and making this watch ready for the future. Keen to see the bracelet and the clasp, from the pictures it does not look as good as the watch itself. Also from a tech point of view i was expecting to see kind of a glide lock...
having looked at it more in depth, it looks like they retained the transparent caseback which looks fine. All in all, a good release!
Slim bezel, optically larger dial (maybe it measures larger too, but all that matters is that it looks bigger), cleaner overall dial and more legible. Have these new models jumped significantly in terms of retail price?
In terms of pricing it jumped quite a bit from 4.900CHF (1861) to 6.250 CHF (3861).
