JackMcLaessig's original post introduced the then-new Omega Speedmaster with the Caliber 3861, sparking a robust discussion among collectors. This article delves into the community's initial reactions, focusing on the nuanced details that define the Speedmaster's heritage and its evolution. Readers will gain insight into the specific features that captivated enthusiasts and the ongoing debates surrounding Omega's design choices.

The Omega Speedmaster Moonwatch Professional, reference 3861, represents a significant evolution within the Speedmaster collection. This reference updates the core Moonwatch design while incorporating modern technical advancements, maintaining its established aesthetic. It is positioned as a contemporary iteration of a well-known chronograph, appealing to collectors who appreciate both heritage design and updated mechanical performance. The model is offered in various material configurations, providing options for different collector preferences.
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
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).
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...
My “collection” is 100% Omega...Seamasters and Speedmasters (which are both ceramic). The speedys are only depth rated to 167 ft. When I asked at the Omega boutique the technician told me “don’t even swim with these”. I have noticed that a few of the 9300 speedys are rated at 10 bar for some inexplicable reason. 1. Why the difference? 2. I wish they would rate the watches at a depth suitable for the pool as if I’m going on a business trip I land up only taking my Seamaster(s) as pool / hot tub e
