What distinguishes it
Look beyond the reference.
The crown’s quick-correction position adjusts the date and GMT indication. This makes it a different operating proposition from a traveller GMT with an independently jumping local-hour hand.
For the enthusiast
The 56-hour figure follows Sellita’s 2024–2025 catalogue. Compare the exact generation when reading older specifications. Its extra central hand needs a 24-hour scale to communicate a second time zone clearly; a rotating bezel can add another reference.
