The Louis Moinet Memoris Spirit LM-84.20.22 is a limited edition of 60 in grade 5 titanium, built around a chronograph mechanism displayed on the dial side. Its automatic LM84 calibre runs at 4 Hz and offers a 48-hour power reserve. The official product page gives its specifications and invites purchase inquiries, but does not publish a current price or live stock status.
What makes the Memoris Spirit different?
Many chronographs hide most of their operating mechanism beneath the dial. The Memoris Spirit reverses that visual emphasis: its chronograph components are arranged on the dial side, where the wearer can see them at work. The Fondation de la Haute Horlogerie identifies the movement as a monopusher chronograph, so the chronograph is operated through a single control rather than separate start/stop and reset pushers.

Louis Moinet describes the case and dial arrangement as a way to keep the mechanism prominent in a relatively compact format. The design uses a convex, two-part dial and a strongly domed, glareproofed sapphire crystal. The brand’s Memoris Spirit backstory explains how the domed crystal and a flange separated from the glass notch helped achieve the intended architecture.

What the specifications mean for a buyer
The 40.7 mm titanium case
The listed diameter is 40.7 mm, and the case is grade 5 titanium. Diameter alone does not establish how the watch will sit on a particular wrist: the sources do not provide a case thickness, lug-to-lug measurement or weight. Trying it on, or confirming those dimensions with a seller, is useful if fit is a deciding factor.
A visible automatic chronograph
The LM84 is automatic, operates at 28,800 vibrations per hour (4 Hz), and has a 48-hour power reserve. The dial-side layout makes the chronograph’s mechanical action a central part of the watch’s appearance. The published specifications describe its architecture, but do not establish model-specific accuracy, durability or service intervals.

Strap integration and water resistance
Louis Moinet lists an alligator strap with a 20 mm width and describes it as specially integrated with the case. That width by itself does not confirm that a standard replacement strap will fit or preserve the intended attachment; check with the brand or a qualified watchmaker before ordering parts. The stated water resistance is 50 m. It is a published specification, not a guarantee of suitability for every water activity or of performance as the watch ages.
Price and availability: what is confirmed?
The official page provides a purchase-request route, not a current public price or live inventory status. Since no current, location-specific authorized offer is established, treat both price and availability as inquiry-only. Ask Louis Moinet or a verified authorized seller to confirm the price in your market, whether a watch is actually available, delivery timing, warranty terms and the seller’s authorized status.

- Confirm strap replacement options with the manufacturer or a qualified watchmaker rather than relying on the listed 20 mm width alone.
- Assess the 50 m water-resistance rating against your intended use and have an appropriate professional explain care and testing for the specific watch.
