In fact, in addition to watches, Citizen also has a business of processing machine tools, electronic equipment, and electronic devices, including blood pressure monitors, the production of which is handled by Dentronix, a subsidiary of the Citizen Group, and its precision and stability can also reach the internationally recognized level.
 
There are many wrist-type blood pressure monitors in Citizen, but compared with the wrist-type blood pressure monitors of Omron and Yuyue, the functionality is not strong, but the price is more than 300 yuan, and the cost performance is not high. Upper arm blood pressure monitor is also lacking in functionality, some styles such as CH-452 in addition to automatic pressurization, average and other more practical functions, CH-550 blood pressure monitor, intimate "mismovement prompt" makes each measurement result very reliable, the display screen is 5 inches, the reading is clear and intuitive, but there is no backlight function, the elderly may look more difficult. The armband storage compartment on the back of the blood pressure monitor greatly improves the convenience of storage. Unfortunately, the disadvantage is also obvious, although it can record 90 measurements, but there is no user data group management function.
 
In recent years, due to the decline of the watch industry and the increase in labor costs, Citizen's business pressure in China has increased, and Citizen Precision Guangzhou has been closed, which is an important production base set up by Citizen Group in China, and is also responsible for the production of blood pressure monitors.
