Citizen · Family: Series8
The Citizen Series8 831 Mechanical GMT NB6034-58L is a 41mm steel watch with a blue dial and a GMT function, part of the Series8 collection Citizen launched in 2021 as its high-end mechanical range, distinct from the Eco-Drive and radio-controlled DNA that dominates the rest of the brand. It runs the automatic calibre 9054, with 24 jewels and 50 hours of power reserve. Against the two Promaster references, the Attesa, and the Tsuyosa already in the catalog, this is the first Series8 and first GMT reference. We have no verified price observations yet (n=0).

Citizen was founded in 1918 in Japan and built much of its international reputation on Eco-Drive technology (light-powered quartz) and its radio-controlled calibers, found in the Attesa and much of the brand's catalog outside Japan.
In 2021, Citizen introduced Series8, a collection explicitly conceived as its high-end mechanical range, with a case design and bracelet-integration language distinct from the rest of the catalog and its own automatic calibers (the 0950/9050 family) instead of Eco-Drive or radio control. The 831 subgroup was positioned as the entry variant within Series8, with a more classic dial aesthetic than the 830.
Reference NB6034-58L expands that 831 subgroup with a GMT function, running calibre 9054 — a second-time-zone variant within the family of mechanical calibers Citizen develops with its Miyota division — with 24 jewels, 50 hours of power reserve, and hacking seconds for precise time-setting.
This reference sets itself apart from the other four Citizen references already in Cazador's catalog — two dive-oriented Promaster watches, the radio-controlled Attesa, and the mechanical integrated-bracelet Tsuyosa — as the first piece from the Series8 range and the first with a GMT function, part of Citizen's more recent push into high-end mechanical watchmaking.

It's the high-end mechanical range Citizen launched in 2021, with its own automatic calibers and a design language distinct from the rest of the catalog, which is dominated by Eco-Drive and radio control.
No. Unlike the Attesa or the Promaster watches already in Cazador, the Series8 831 runs its own automatic mechanical caliber, with no quartz or time-signal reception.
An independent hand travels around a 24-hour scale on the dial, letting the wearer read a second time zone alongside local time.
50 hours, with 24 jewels, hacking seconds, and antimagnetic protection.
The Tsuyosa is a mechanical integrated-bracelet watch within Citizen's general catalog; the Series8 831 belongs to a distinct range positioned as the brand's high-end mechanical proposition, and this reference adds a GMT function.
