A new Citizen watch, referred to as the 'Eco-Zilla' 300M, is being discussed. However, it is unclear if this is the same watch as the Citizen 'Orca' mentioned in another report, which is described as a dive watch available for under $500. The 'Eco-Zilla' 300M is being compared to other watches, including a Seiko model, as part of a broader discussion of dive watches available for under $1,000.
