The differences between the Citizen automatic vs eco drive and Seiko Solar are not that great. The case size and case back of the Citizen is slightly smaller than the Seiko Solar’s, though both have solid casebacks. The case is 40mm in diameter. The battery in the Citizen Eco-Drive is less powerful than the one in the Seiko Solar, but it retains up to 85% of its charge life.
How to Choose Citizen Eco-Drive Vs Seiko Solar
The main differences between the two brands are the price and the battery life. The Seiko Solar is more expensive than the Citizen Eco-Drive, but the former has more advanced solar technology and is available in more popular models. Both have stellar track records and are a good choice if you want an affordable quartz timepiece. However, the latter is limited to a few Seiko watches and is not as durable.
Both brands make watches that use solar power to charge their batteries. The Seiko Solar line is known for its long-lasting batteries, but the Citizen Eco-Drive is more efficient than the Seiko. The former makes it easier to recharge the battery and is a better choice for those who want a high-quality watch. The Seiko Eco-Drive can run for several months without charging, while the latter has Bluetooth capabilities.
