GrailAtlasAn independent reference for mechanical watches

Series 8

Citizen’s mechanical sport line — launched 2021 to re-establish the brand’s 1970s "Challenge Timer" and "Leopard" mechanical heritage. The 870, 880, and 831 GMT references use Citizen’s in-house 9051/0950/9054 calibers — the rare mechanical carve-out in a brand catalog otherwise dominated by Eco-Drive quartz.
