The title’s “fourth edition” claim is not confirmed by the available official information. Montblanc’s US product page identifies the Star Legacy Orbis Terrarum reference MB128675, but does not call it a fourth edition or provide a launch announcement. The documented watch is a 24-time-zone world timer with a day-and-night display; its relationship to the claimed edition remains unverified.
Is this the fourth edition of the Star Legacy Orbis Terrarum?
Montblanc’s official US listing confirms the Star Legacy Orbis Terrarum reference MB128675, but it does not identify that watch as a fourth edition. The available materials do not establish a reference number, release date, edition size, price, market, or design changes for a newly launched fourth edition. The confirmed MB128675 should therefore not be presented as that edition without an announcement linking them. Montblanc’s US product listing documents the reference, not the claimed launch.
Watch Collecting Lifestyle reports that the line was first revealed in 2014 and describes three configurations: blue with stainless steel, brown with rose gold, and a green limited edition for the United Arab Emirates. That is a secondary publication’s account, not an official or exhaustive catalog, and it does not verify a fourth release. Watch Collecting Lifestyle’s overview is the source for that chronology and configuration count.
How the confirmed MB128675 world-time display works
Montblanc describes MB128675 as an automatic watch with a manufacture world-time complication covering 24 time zones. Its display combines a map, city ring and day/night indicator:
#1 Best Overall
- Montblanc Spirit Orbis Terrarum Asian UNICEF Automatic Watch 116534
- A rotating upper sapphire disc carries a three-dimensional Northern Hemisphere map and meridians.
- A surrounding ring names 24 cities, representing the watch’s time-zone display.
- A 24-hour disc beneath the map alternates light and dark to show day and night.
- A single pusher sets the world-time function when travelling.
These are manufacturer-published descriptions; no hands-on assessment of the mechanism or operation is established here. Montblanc explains “Orbis Terrarum” as Latin for globe, earth and world.

Montblanc says the Star Legacy line takes inspiration from Minerva heritage and the company’s late-19th- and early-20th-century pocket watches. Those collection influences do not establish what, if anything, distinguishes a fourth Orbis Terrarum edition.
