Otherwise, the pair share the same basic dimensions and key specifications: both are hand-wound, 41 mm mechanical watches with a stated 60-hour power reserve and 50 m / 5 ATM water resistance, according to Leica. Choose the ZM 2 if you will use its extra time-zone information; the ZM 1 is the simpler choice if you will not.
How the ZM 1 and ZM 2 differ
Leica describes the ZM 1 as having five functions and the ZM 2 as having seven. The ZM 2’s two additions are an inner GMT ring for tracking a second time zone and a day/night indicator synchronized with that display. The distinction is practical rather than a difference in size or basic timekeeping.
| Feature | Leica ZM 1 | Leica ZM 2 |
|---|---|---|
| Functions, as listed by Leica | Five | Seven |
| Second time zone | Not listed | Inner GMT ring |
| Day/night display | Not listed | Synchronized with the GMT display |
| Caliber | LH-10 | LH-20 |
Leica’s technical specifications give both watches hours, minutes, small seconds, a date display with quick setting, a power-reserve indicator and a push-crown setting mode. The ZM 2’s extra indications are most useful to someone who regularly coordinates with another time zone; they do not establish that it is more accurate or mechanically superior.
Shared specifications
Leica lists the following core specifications for both models on its technical pages. These are manufacturer-published figures, not independent test results.

The standard case is listed as 316L stainless steel, with a domed sapphire front crystal and flat sapphire case-back crystal. Leica also lists Monochrom versions with black PVD-coated stainless-steel cases and black styling. The technical pages describe the ZM 1 and ZM 2 calibers as made in Germany; Leica says the movements and watch components are manufactured in Lehmann Präzision’s workshop.
How the push-crown setting mode works
Unlike a conventional crown that is pulled out, Leica’s patented push-crown is pressed to enter the time-setting mode. Leica says this action resets the small-seconds hand to zero, while a circular status indicator turns red. The company says the control was inspired by the release of a camera shutter. The description explains the intended operation, but does not substitute for trying the control or consulting the watch’s instructions for use.

Which model should you choose?
Choose the ZM 1 if
- You mainly want the shared time, date and power-reserve functions.
- You do not expect to use an additional time-zone display or its day/night indication.
Choose the ZM 2 if
- You want to read a second time zone on the watch using its inner GMT ring.
- The synchronized day/night indication is useful for distinguishing the second zone’s time of day.
The specifications establish the extra functionality, not a general value advantage. The official material does not provide independent accuracy measurements, comparative comfort or durability testing, or service-cost figures, so those factors cannot be used to distinguish the models here.
Variants, availability and documented prices
Leica lists standard and Monochrom versions; the Urban Green versions add another design option. In its 28 May 2025 announcement, Leica described Urban Green’s dial as a green-to-black gradient and specified a stainless-steel Milanese strap. The same announcement said the ZM 1 Urban Green and ZM 2 Urban Green became available globally that day through selected Leica stores and Leica’s online store.

Leica’s recommended retail prices at that Urban Green launch were €10,800 including VAT for the ZM 1 Urban Green and €14,600 including VAT for the ZM 2 Urban Green. These are dated launch prices for those specific variants, not a current price list for every version or region. Check Leica or a selected retailer for present pricing and stock. Leica describes the watches as limited in availability; that is the manufacturer’s characterization, not a confirmation of current inventory.
The available official information identifies different case and dial treatments, but does not establish comparative strap or buckle configurations for every model and variant. Confirm the exact configuration for the reference you are considering with Leica or the retailer.

What the specifications do—and do not—tell you
On paper, the watches share a compact set of core specifications and differ most clearly in the ZM 2’s second-time-zone display. A 41 mm diameter and 14.5 mm height describe the case, but do not establish how either watch will fit a particular wrist. Likewise, the stated water resistance is a manufacturer specification, not an independent water-resistance test. If fit, accuracy, maintenance or real-world durability will determine your decision, those questions require information beyond the published specifications.
