Shown in late 2013 and reaching the market in 2014, the Grand Lange 1 Moon Phase moves the moon-phase display into the off-center hour/minute subdial itself, rather than tucking it into a corner register. That placement is only possible because the Grand Lange 1 case is larger, 41mm against the standard Lange 1's 38.5mm. The yellow gold 139.021 pairs that dial with the manually wound caliber L095.3 and its 72-hour reserve.

- The moon-phase disc sits inside the hour/minute subdial rather than in a separate register, a layout only the larger Grand Lange 1 case accommodates.

How do I check a A. Lange & Söhne 139.021 with Watch Safe?
Look up the watch's serial number in the Watch Safe registry to see whether a record exists or a theft flag is attached. A registry search identifies records for a specific serial; it does not authenticate the watch. Authentication is performed in person by an independent expert authenticator, and Watch Safe records and publishes the result.
