The standard model measures 39 mm, while Tefnut 36 versions use a 36 mm case; their movements, seconds display, materials and straps also differ. For a dated price reference, Monochrome Watches reported EUR 29,000 excluding VAT for the limited 2026 Tefnut 36 MG-004153. That figure applies to that reference, not the collection as a whole.
Which Moritz Grossmann Tefnut is this?
The collection includes the standard Tefnut, Tefnut 36, Tefnut Lady, Tefnut Twist and jewellery variants. Specifications below focus on the standard 39 mm model, the gold-case Tefnut 36 versions listed on the manufacturer’s English page, and the 2026 Tefnut 36 Silver-Plated by Friction Turquoise Blue, reference MG-004153. These should not be treated as interchangeable versions. See the manufacturer’s Tefnut collection for the family overview.
The title’s “hands-on” and “live photos” wording should not be taken as evidence of a physical inspection or original photography. The images available through Moritz Grossmann’s press page are manufacturer imagery; they are not independent wrist photographs.

What the movement specifications mean
Calibre 102.1 in the standard Tefnut and MG-004153
Moritz Grossmann lists calibre 102.1 as a manually wound movement with 188 parts, 22 jewels—including three in screwed gold chatons—a lever escapement and a 10 mm Grossmann balance. Its stated frequency is 21,600 semi-oscillations per hour, and its power reserve is 48 hours. The standard model and MG-004153 share this calibre, but their case dimensions and materials are not identical.
Calibre 102.0 in the listed gold Tefnut 36
The gold Tefnut 36 versions use manual calibre 102.0, listed with 196 parts, 26 jewels—including three in screwed gold chatons—and a lever escapement. The manufacturer states a 48-hour reserve. Unlike the standard Tefnut and MG-004153 specifications, this version’s display includes subsidiary seconds.

That difference matters when comparing photographs or listings: subsidiary seconds are not a universal Tefnut feature. The official 2026 MG-004153 page specifies hours and minutes, while Monochrome’s launch coverage describes small seconds at 6. Confirm the display on the precise reference shown rather than assuming all 36 mm watches share the gold versions’ layout.

What to verify before comparing or buying
- Reference: Confirm the full reference number; collection name alone does not identify the case, dial or movement.
- Dimensions: Distinguish the 39 mm standard Tefnut from 36 mm variants, and check thickness as well as diameter.
- Movement and display: Check whether the watch has calibre 102.1 or 102.0 and whether the listed configuration includes subsidiary seconds.
- Materials and finish: Verify case metal, dial treatment and hands for that reference rather than applying details from another Tefnut.
- Strap and clasp: The documented variants use alligator or kudu straps and different buckle materials. Do not assume a generic replacement strap will fit; confirm dimensions and fitting with a watch specialist.
- Price and availability: Treat the MG-004153 report as dated reference information, then request a current quote in the relevant market.
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
