Description

La batterie rechargeable Citizen MT621 295-5100 est un composant d'origine conçu pour les montres Citizen dotées de la technologie de recharge propriétaire. Avec une tension de 1.5V et une capacité de 2.5mAh, ce composant garantit l'alimentation stable du mouvement quartz de votre montre. C'est le choix idéal pour maintenir les performances de votre montre Citizen sur la durée.

Spécification et compatibilité du composant

La batterie MT621 référence 295-5100 s'intègre dans les systèmes de recharge Citizen spécifiquement conçus pour cette tension et cette capacité. L'utilisation d'une batterie d'origine garantit une compatibilité électrique et mécanique optimale avec votre mouvement. Avant toute intervention, vérifiez que votre montre correspond bien à cette référence dans la documentation constructeur ou auprès d'un horloger agréé.

Recharge et longévité du composant

Contrairement aux piles traditionnelles, la batterie rechargeable MT621 se régénère grâce au système d'exposition à la lumière intégrée dans votre montre Citizen. Un fonctionnement régulier (port quotidien ou exposition à la lumière naturelle) prolonge la durée de vie utile du composant. Les batteries rechargeables se dégradent progressivement ; après 2 à 3 ans d'utilisation intensive, une baisse d'autonomie est normale.

Installation et entretien

Le remplacement de la batterie MT621 nécessite l'intervention d'un horloger professionnel disposant des outils adaptés. Après installation, laissez votre montre exposée à la lumière pendant plusieurs heures pour amorcer la première charge complète. L'entretien régulier (exposition à la lumière, vérification annuelle de l'étanchéité) assure le bon fonctionnement du système de recharge.

Frequently asked questions

How long does it take to replace the MT621 battery at a watchmaker ?
Replacing the Citizen MT621 rechargeable component (reference 295-5100) typically takes between 24 and 72 hours depending on the watchmaker's workload. The service includes opening the case, removing the worn battery, installing the new component, and verifying water resistance. We recommend entrusting this operation to a Citizen-approved watchmaker to ensure quality work and preserve your manufacturer warranty
Is the MT621 battery 295-5100 compatible with all Citizen models ?
No. The MT621 battery (reference 295-5100) is specific to certain Citizen calibres. Before ordering, verify your movement's calibre number (visible on the case back or in your original documentation). A watchmaker can confirm compatibility. Using an incompatible component risks damaging the movement and compromising your watch's function
What is the lifespan of a Citizen MT621 rechargeable battery ?
A MT621 component in good condition typically operates for 3 to 5 years depending on usage intensity and storage conditions. After this period, performance gradually declines (reduced capacity, voltage drift), resulting in loss of accuracy or unexpected stops. Preventative replacement every 4 years maintains your Citizen watch's reliability and prevents unexpected failures
Should I keep the old battery after replacement ?
No. The old MT621 rechargeable component must not be discarded as ordinary waste. Like all electronic components, it falls under the Waste Electrical and Electronic Equipment (WEEE) recycling scheme. Your watchmaker can handle its disposal, or you may drop it at an authorised collection point. This is an important environmental responsibility
Can I replace the MT621 battery myself ?
No. Replacing the Citizen MT621 rechargeable battery requires specialised tools (watchmaker's screwdrivers, press, tester) and knowledge of the specific movement. Poor workmanship risks permanently damaging the calibre, deteriorating water-resistance seals, or scratching the case. Entrust this operation to a professional Citizen-approved watchmaker to protect your watch
Is the MT621 battery covered by Citizen's warranty ?
The Citizen MT621 rechargeable battery (reference 295-5100) is not covered by the 2-year manufacturer's warranty, as it is a consumable component subject to natural wear. Citizen's warranty covers only manufacturing defects in the movement itself. Battery replacement is routine maintenance at the owner's expense. However, if the battery shows a manufacturing defect before first use, contact Citizen's after-sales service for assessment
How long does delivery take?
Order shipped within 24-48 working hours. Standard delivery in mainland France: 2-5 working days, free from €69. Belgium, Switzerland, Luxembourg, Germany: 3-7 working days.
Is this watch authentic and new?
100% authentic and new. Each watch comes from official end-of-series collections or authorized European distributors. Delivered in its original box with the international manufacturer warranty.
What is the warranty?
2-year international manufacturer warranty included. It covers manufacturing defects in the movement. Our customer service handles the whole process with the brand.
Can I return or exchange my order?
Yes, you have 14 days to change your mind from receipt, no justification needed. The item must be new, unused, in its original packaging. Easy return via your customer account.
How do I adjust the strap to my wrist?
For metal bracelets, any watchmaker can remove links in minutes. Leather and silicone straps have multiple adjustment holes. A full guide is available in our maintenance guide section.
What payment methods do you accept?
Credit card (Visa, Mastercard, CB), PayPal, Klarna (pay in 3 or 4 interest-free installments). All payments secured by Stripe, PCI DSS standard.
