Name: Nomos Glashütte Metro Date Power Reserve 1101
Brand: Nomos Glashütte
SKU: 1101

The Metro Date Power Reserve (ref. 1101) is designer Mark Braun's contribution to the Nomos catalog, a 37mm city-watch with the brand's DUW 4401 in-house automatic caliber, a hair-thin minute track, a small-seconds register at six with an integrated date aperture, and a graphic power-reserve indicator at twelve. Among Nomos's core lines it is the most-decorated; among the brand's automatic references it carries the strongest in-house movement.

What it is

Nomos introduced the Metro in 2014 with the original time-only design by Mark Braun; the Date Power Reserve generation followed shortly after with the DUW 4401, the brand's first automatic caliber to integrate a date module on the same plane as the going train (in place of a stacked module). The result is a 7.5mm-thick movement carrying complications that would normally drive a 9mm+ profile in a Sellita-based reference. The 'Tiefblau' (deep-blue) and 'Champagne' dial variants are the most-traded; the original time-only Metro (without the date and power-reserve) remains available as a smaller-format alternative.

Buying notes

Common things to check: papers (a Metro at this price tier is fine without papers but the Nomos card adds modest value); date alignment (the integrated date sits inside the small-seconds register at six, alignment between the date wheel and the printed date frame is a service-quality check); power-reserve calibration (the indicator at twelve should read full at end-of-wind and empty after 42-44 hours, a miscalibrated indicator is a real-world annoyance but a straightforward service item); caliber DUW 4401 (verify the integrated date module through the case-back); dial originality (the printed-and-painted graphic style does not refinish well, verify printing under loupe).

Market read

Metro Date Power Reserve examples trade in the $2,600-$3,400 range through 2025-2026, against a current retail of approximately $3,800. The reference has been one of the catalog's steadier mid-range positions, the design is divisive enough that it does not move fast at retail, but the secondary market for the released examples is consistent. The 2025 'Tiefblau' release has held value better than the earlier color variants.

Service expectations

Service is Nomos-direct in Glashütte or through the brand's authorized service centers. Expect 4-6 month turnaround and a low-to-mid-four-figure service bill. The DUW 4401 is well-understood by the brand's service department; service intervals of 6-8 years are typical.

Authentication guide

Last reviewed June 2026

The Metro Date adds a date complication and power reserve display to the Metro's round case with curved sapphire crystal. Cal. DUW 4401 is an in-house automatic with date. The curved crystal is a key Metro identifier, and Glashütte stripes through the caseback confirm the movement.

MEDIUM

Cal. Alpha manual-wind movement fitted in Metro Date case

No rotor through caseback -- Alpha is manual-wind; DUW 4401 has an oscillating weight
Caseback marking showing "Cal. Alpha" or "DUW 1001" rather than "DUW 4401"
Power reserve sector at 3 that does not advance with wear, indicating no winding mechanism

The Metro family has multiple variants including manual-wind options. The key check is that ref. 1101 specifically uses DUW 4401 automatic with date and power reserve.

Dial variants by era

Era	Description	Identifiers
2014 to present	Round 37mm case with a curved sapphire crystal that follows the dial dome. White, silver, or grey dial with applied hour indices. Date window at 6 with no cyclops. Power reserve arc at 3.	Curved sapphire crystal: the Metro has a domed crystal profile that follows the case curvature, unlike the flat crystal on Tangente or Orion families Applied hour indices rather than printed numerals -- the Metro uses applied markers at 12, 3, 6, 9 with printed chapter ring Date window at 6 with square aperture and no magnification Power reserve arc at 3, graduated as a sector indicator "NOMOS Glashütte" at 12, "DATUM GANGRESERVE" or "DATE POWER RESERVE" in smaller text below

Curved crystal

Original: The Metro uses a curved sapphire crystal with a radius matching the case curvature. The dome is subtle but visible in profile. A flat replacement crystal will alter the watch silhouette and is immediately apparent when compared to a reference example.

Replacement tells

Flat sapphire crystal on a Metro case -- the Metro crystal has curvature that a standard flat replacement will not replicate
Crystal with visible flat edge on the underside where it meets the dial at the edges
Any mineral glass replacement rather than sapphire

Movement (Cal. DUW 4401)

Original: In-house automatic with date, 28,800 vph (4Hz), 42-hour power reserve. The Swing System escapement is Nomos's proprietary lever escapement, developed in-house. The bidirectional winding rotor is visible through the caseback with conventional oscillating weight profile.

Replacement tells

Movement without Glashütte stripes -- confirms non-Nomos caliber
No rotor visible through caseback -- DUW 4401 is automatic; any manual-wind movement is incorrect
Beat rate different from 4Hz: the seconds hand advances in 1/8-second steps rather than 1/6-second steps of 3Hz movements
Movement bridge marked with "Alpha" or "DUW 6101" designations rather than "DUW 4401"

Movement tells

toggle

Power reserve is 42 hours. The arc indicator at 3 should reach empty in approximately 42 hours without winding. Dropping to reserve before 36 hours indicates mainspring or winding mechanism service.
Beat rate is 28,800 vph (4Hz). The seconds hand steps in 1/8-second increments, producing a slightly smoother sweep appearance than the 3Hz Alpha. Counting beats over 30 seconds should give approximately 240 beats for a properly regulated watch.
The date advances at midnight. Rapid-advance date via the crown at position 2 should click through dates cleanly without slipping.
