CITIZEN has made all Instruction manuals in PDF format available for download from the global site for several years now, and no longer comes with a BOOK.
So, the small instruction booklet is not included and the instruction manual is a PDF file.
However, perhaps because this model is limited to Japan, there is only a Japanese instruction manual (PDF).
mechanical diver 200m
Go Deeper To the depths of the ocean that you can never reach no matter how deep you dive. A full-scale diver's watch. Promaster "MARINE series".
Introducing a mechanical diver's watch that inherits the design of the legacy model, which was discovered on an Australian beach in 1983 and was loved as a "barnacle diver" because it worked even though it was covered in barnacles. The specifications and materials have been modernized, including excellent magnetic resistance of 16000A/m and a comfortable fit with a reduced case thickness. The glossy black exterior uses Duratect DLC, which is tough and resistant to small scratches. The gradation dial changes from gray in the center to black, representing a scene where sunlight shines faintly into the darkness of the ocean. The frames of the hands and indexes are also finished in black, creating a unified design.
Scratch-resistant, lightweight, and rust-resistant
``Super Titanium'' is a material made using unique titanium processing technology and surface hardening technology (Duratect). It is 40% lighter than stainless steel and has a surface hardness 5 times more.
Preventing time lag due to magnetic force
In order to prevent time lag due to magnetic force emitted from smartphones, tablets, etc., the watch is equipped with "Type 2 anti-magnetic" technology, which has enhanced anti-magnetic performance. In most cases, it is possible to maintain performance even when placed as close as 1 cm to devices that generate magnetic fields.
