Choosing or documenting a Maurice Lacroix watch starts with three identifiers: the collection, the full reference, and the movement or caliber. The collection helps you navigate the designs; the reference and movement determine which specifications and instructions belong to the watch in front of you.
Use the brand's history as a map of design choices
Maurice Lacroix's 2025 account of the 1975 collection traces the brand to 1975 and describes two different uses of its archive. The Calypso influenced the AIKON, introduced in 2016, while the 1975 collection revisited Les Classiques designs introduced in 1988. The same account highlights Masterpiece experiments such as Square Wheel, Mysterious Seconds, and Gravity.
Those examples give you a useful reading strategy. Look at how a watch displays time, how the case meets its strap or bracelet, and what the movement adds to the experience. A familiar brand name can encompass conventional displays, visually unusual mechanisms, and different power sources.
For the current range, start at the official Maurice Lacroix collection index. Model availability and collection membership can change. Use historical names to investigate an older watch, and its actual reference to check the details.
A dated example: similar looks, different references
The March 25, 2025 announcement supplies a compact lesson in reference matching. Its launch examples include both quartz and automatic 1975 watches. The table describes those documented examples, rather than the entire current range.
Scroll horizontally to see all columns.
| Reference | Documented configuration | Ownership question |
|---|---|---|
| 751007-SS001-130-3 | 1975 Quartz, 39 mm case. | What battery service and instructions apply to this movement? |
| 756007-SS001-130-3 | 1975 Automatic, 36 mm case. | How should this caliber be wound and set, and does the smaller case fit comfortably? |
| 756008-SS001-130-3 | 1975 Automatic, 40 mm case. | How does the complete case and strap fit compared with the 36 mm version? |
Copy the complete reference, including the suffix. A shortened collection name loses information. Compare dial, case, bracelet or strap, and any documented substitutions. When buying used, ask which parts are original to the sale configuration and which were replaced during service.
Fit includes lug-to-lug length, case thickness, clasp position, and how the strap bends around your wrist. Try the actual watch or a close dimensional match. The everyday watch guide provides a repeatable fit and legibility check.
Find the instructions before operating an unfamiliar watch
The manufacturer's manual page separates standard automatic/quartz instructions from manufacture-movement manuals, including a specific Cinq Aiguilles document. That structure is a useful reminder to identify the movement before borrowing another watch's setting procedure.
- Record the full case reference, visible movement information, and private serial number. Photograph the dial, caseback, and paperwork.
- Find the relevant manual family and locate the function layout that matches the watch. Check crown positions, pushers, calendar displays, and any setting restrictions.
- Save the PDF with its title and retrieval date. Keep the original file, so diagrams and warnings remain together.
- If the movement or layout is uncertain, send the reference and photographs through the official service route and ask which manual applies.
- Follow the confirmed manual in sequence. Stop if a control resists or behaves differently from the instructions and seek service advice.
A movement visible through a caseback can help with identification, but a photograph alone leaves many condition and authenticity questions unresolved. Ask what the proposed inspection includes and which conclusions it can support.
Read unusual displays on their own terms
With a conventional watch, the main reading task is locating the hands. An unusual display may ask you to follow a moving element, a returning indicator, or a different arrangement of the time scale. Before comparing specifications, watch the manufacturer's demonstration and explain to yourself where hours, minutes, and seconds are shown.
Keep the visual experience and timekeeping evidence separate in your notes. A distinctive mechanism can be the reason you enjoy the watch; any accuracy claim still needs a stated test, duration, conditions, and applicable model. The tourbillon explanation demonstrates why complicated motion and measured performance answer different questions.
Prepare a service request that answers a specific problem
Maurice Lacroix's service information is the starting point for available work and regional pricing. Confirm the location, movement category, parts availability, and exact scope before using a listed amount as your budget.
Describe the symptom with observations: when it began, whether the watch stopped or changed rate, what functions are affected, and any impact or water exposure. For a rate observation, record the starting offset, elapsed interval, ending offset, and reference clock. Avoid changing several conditions while collecting the example.
The manufacturer's care advice covers handling, water resistance, magnetic fields, and servicing. Apply the actual model's limits and its present condition. Keep invoices and test results with the watch record, and agree on cosmetic refinishing or replacement parts as part of the estimate.
