Switzerland’s independent watchmaker Speake-Marin has added a striking new colourway to its Openworked collection. The Dual Time Mint pairs a skeletonised dial with a fresh mint green finish, aiming squarely at collectors who want a dual time watch that stands out rather than blends in. The piece is listed in India through Ethos Watch Boutiques at an MRP of ₹44,10,000.
What Makes the Dual Time Mint Different
The Openworked collection takes cues from contemporary architecture, using angular lines and geometric patterns to expose the movement underneath. The Dual Time Mint carries this design forward with a mint green skeleton dial, spade hands, and Arabic numeral indexes. A small seconds subdial sits asymmetrically between the one and two o’clock markers, a signature Speake-Marin layout choice that keeps the exposed mechanism visible while breaking from a conventional dial arrangement.

The watch is built for travellers. Its dual time function shows a second time zone through a dedicated subdial while the main Speake-Marin hands track home time, making it practical for anyone who splits time across regions.

Design Heritage: The Openworked Collection

Speake-Marin, founded by British watchmaker Peter Speake-Marin in 2002 and based in Geneva, built its reputation on the Piccadilly case, a design the brand has updated for the Openworked line with a slimmer profile and more ergonomic lugs. The collection spans time-only pieces up to tourbillon complications, but the Dual Time models, including this Mint edition and a companion Lime colourway, add functional travel utility to the brand’s skeletonised design language.

Should You..
The Dual Time Mint suits collectors already familiar with independent Swiss watchmaking who want a dual time piece with visible mechanics rather than a closed dial. The mint green finish is a deliberate departure from typical skeleton watch colourways, and the 38mm case keeps it wearable rather than oversized. At this price point, it competes with entry-level independent haute horlogerie rather than mainstream luxury sports watches.
