Rolex GMT-Master IIModel No: 126710BLNR

The blue and black split on the Batman bezel carries a functional meaning: the two-colour Cerachrom insert divides the 24-hour scale into its day half and night half, so the arrow-tipped 24-hour hand shows not only the reference city's time but whether it is light or dark there at a glance. The 40mm Oystersteel monobloc Oyster case carries a Triplock screw-down crown, the additional complexity of the Triplock system providing triple waterproofness to 100 metres against the Twinlock's double system. The Cerachrom insert is virtually scratchproof, its moulded numerals and graduations unaffected by surface wear. The sapphire crystal carries a Cyclops lens over the date at three o'clock.

Rolex describes the GMT function on the official page directly: the 24-hour hand displays home time against the bezel's fixed scale, and the local time hour hand jumps forwards or backwards independently of the minute and seconds hands via the crown. Precision is maintained throughout the adjustment. The black dial carries Chromalight hour markers and hands with long-lasting blue luminescence.

At Second Movement, the pre-owned division of Ethos Watches, we adhere to a rigorous verification process where expert watchmakers carefully inspect every watch to certify its authenticity, ensuring it is not counterfeit. We also go to the maximum extent possible to ensure that the timepiece is not a stolen property and that all duties are paid. However, in the absence of any central database, a 100% verification is unlikely for any pre-owned entity in India. Nevertheless, we can still provide a provenance guarantee for watches purchased from Ethos.
