There are some factories and workshops in Hanoi engaged in watch assembly and component processing. Although the industry is not as mature as in Switzerland or Shenzhen, China, local production capabilities are gradually improving with the development of Vietnam's manufacturing sector. Some local watch enthusiasts and small workshops in Hanoi offer customization services, such as replacing watch cases, dials, hands, and movements, to meet customers' personalized needs. Hopefully, the custom watch industry in Hanoi will continue to grow and thrive.
