Question 1

What is the difference between an automatic movement and a Citizen Eco-Drive movement?

Accepted Answer

An automatic movement (such as the Calibre 8210 in the Tsuyosa) winds itself through wrist movements. It offers a smooth seconds hand and mechanical charm, but needs to be worn regularly or wound manually. Eco-Drive converts any light source (natural or artificial) into electricity, stored in a rechargeable battery. It never needs a battery change, offers quartz precision (±15 seconds/month) and can remain stopped for several months in reserve. The choice depends on your relationship with horolo

Question 2

Can I swim with a Citizen Promaster watch?

Accepted Answer

Yes, Promaster models display 200 metres water resistance (20 ATM), making them suitable for scuba diving up to 200 metres maximum (ISO 6425 standard). You can swim, snorkel and leisure dive without issue. Caution: avoid manipulating the crown underwater, and rinse the watch with fresh water after sea bathing. Non-Promaster models (such as Eco-Drive Chronographs) have 50 to 100 metres water resistance: suitable for swimming but not diving.

Question 3

How do I maintain my Citizen Eco-Drive watch?

Accepted Answer

Maintenance of an Eco-Drive movement is minimal. Expose the watch to natural light for a few hours each month to maintain the charge reserve. Avoid extreme temperatures (under a car bonnet in summer). Clean the case and bracelet with a soft cloth and warm soapy water. Every 3 to 5 years, a check with an authorised watchmaker (crown seal replacement, water resistance test) is recommended, costing around €50-80. Unlike a mechanical watch, there is no oil change necessary.

Question 4

How do I choose between a Citizen Tsuyosa and a Citizen Promaster for everyday use?

Accepted Answer

The Tsuyosa (40mm case, automatic, sapphire crystal) is ideal for office or smart casual use. Its clean design and integrated bracelet make it versatile with formal or casual wear. The Promaster (44-48mm, Eco-Drive or automatic, 200m water resistance) is sportier and more substantial. It suits casual or outdoor style better. If you are looking for a versatile and elegant everyday watch, choose the Tsuyosa. If you practise water activities or prefer a robust look, opt for the Promaster.

Question 5

What is the difference between a Citizen Attesa and a standard Citizen?

Accepted Answer

The Attesa is Citizen's premium range, primarily marketed in Japan and certain Asian markets. It stands out through: a Super Titanium™ case (ultra-light and scratch-resistant), a radio-controlled movement (reception of atomic time signals for second-perfect precision), a sapphire crystal with double anti-reflective coating, and 100 metres water resistance. Finishes are more refined (contrasting polishing, complex dials). The price (€500-800) reflects this step up in range. Standard models (Proma
