Brand Guides / Montblanc / Montblanc Star Legacy
Reviewed by the Fine Watch Guide team · October 2026
Star Legacy is Montblanc's reworked Star collection from 2018, a round watch with pebble-like cases and Minerva-inspired details, and its Automatic Date runs on the MB 24.01 caliber.
Star Legacy is the Montblanc family most often described as a dress watch, and it sits between the brand's pen-maker roots and the Minerva history it borrows from. The Star line dates to 1997, and the reworked Star Legacy appeared in 2018 with rounded pebble-like cases and details taken from historic Minerva pocket watches. Owners tend to ask two things: which movement is inside, and how much of the watch is still original.
Montblanc dates the roots of the Star collection to 1997, and the line it introduced became the base that the house later built on. Some present-day descriptions apply the Star Legacy name back to that 1997 origin, which can make the history look more continuous than it was. The 2018 reworking is the version most owners mean when they say Star Legacy.
Montblanc linked the 2018 design to Minerva and cited late nineteenth and early twentieth century pocket watches, including a 1927 Gold Hunter. The influence shows in the rounded, pebble-like cases, the stepped lugs, the onion-shaped crowns, the leaf-shaped hands and the traditional minute track. It is a design citation, and it does not mean that every Star Legacy contains a Minerva movement.
The 2018 relaunch was shown at SIHH, and the family has since offered variations in size and layout. The reference identifies a particular watch far more reliably than the collection name, so the reference is the first thing to write down when you look at one.
The Star Legacy Automatic Date, shown in 2018 in a 42 mm reference 116511, runs on the MB 24.01. Montblanc's published figures give automatic winding, a frequency of 28,800 vibrations per hour (4 Hz), central hours, minutes and seconds, and a date at six o'clock. The power reserve is about 42 hours, so a watch left off the wrist over a weekend will stop, and that is worth knowing before you choose a winder or a travel routine.
Montblanc's service route runs through its boutiques or an authorized repair partner. Ask the workshop to confirm in writing what the service includes and whether the watch will be sent to the Swiss manufacture. Because a Star Legacy has a case, a bezel and often a bracelet as well as a movement, the quote should separate the movement work from the case and bracelet work.
Ask any independent whether it can source parts for the MB 24.01 before you hand over the watch. That answer decides whether the watch can stay with a local workshop or has to go to the brand, and the answer should be in writing before the work begins.
The date mechanism deserves a look as well. A date that changes late, or that sits between two numbers, usually points to a setting issue that is simple to correct but should be corrected before the watch is sold. Ask the workshop to check the date change at several points in the day, confirm that the hands return to their correct positions after a manual set, and record the result on the service paperwork.
Start with the reference and check the caliber against it. An Automatic Date with the MB 24.01 should show hours, minutes, seconds and a date at six o'clock. A listing that describes a different movement or a different date window needs an explanation. Compare the case diameter with the reference as well, since the family has come in more than one size.
The dial and hands are the next layer. Check the hands for alignment, the date for correct setting and the seconds hand for smooth movement. A dial that has been refinished or reprinted can look fine in a photograph and still change the value, so ask whether any part has been replaced and request the original box and papers.
Case condition matters because the pebble shape is made of curved surfaces, and polishing changes those curves. A case that has been refinished several times looks softer, and a seller should be able to say whether that has happened. A written condition report from an independent gives you something concrete to compare the listing against, and it is worth the cost on a watch like this.
Ask for the bracelet, if the watch has one, to be checked for play at each link and for the clasp to be tested. A bracelet worn for years develops loose links that rattle, and a loose bracelet changes how the watch sits on the wrist as much as a worn strap does.
The pebble-like case reads best when its curves are crisp, so polishing should be kept to a minimum. Ask the workshop to show you the case before and after any refinishing, and ask what the work removed. A small amount of work on a case that needs it is a fair choice, but repeated work is hard to undo.
Straps and bracelets are the parts owners replace most often. Keep the original, and record which one came with the watch. A replacement strap changes the look and sometimes the fit, so a note in the box helps the next owner understand what the watch wore when it was made.
Keep the box, papers and any service record together. A complete set makes the watch easier to value and easier to sell, and a service record that names the work done is the best evidence that the movement has been looked after properly.
The reworked Star Legacy appeared in 2018. Montblanc dates the Star collection it grew from to 1997.
It uses the MB 24.01, an automatic with a frequency of 4 Hz and a reserve of about 42 hours, according to Montblanc's published figures.
Montblanc cites Minerva pocket watches, including a 1927 Gold Hunter, as design inspiration. That influence is in the design, and it does not mean every Star Legacy contains a Minerva movement.
You can, but polishing removes metal and softens the pebble-like curves. Ask for the minimum work and keep a record of what was done.
