Frequently asked questions
What is the lug width of the Citizen Eco-Drive BU2013-08E?
The Citizen Eco-Drive BU2013-08E features lug width of 23mm, measured between the inner shoulders of the spring bar terminals. This measurement is an established standard for 44mm Citizen chronographs and is compatible with a broad range of aftermarket straps available from specialist retailers.
What is the best strap for the Citizen Eco-Drive BU2013-08E?
Selection depends on intended use: for formal or mixed contexts, vegetable-tanned leather in brown or cognac tones is recommended; for sporting activities and humid environments, a ballistic nylon NATO in black or grey offers resilience and practicality; for maximum versatility, vulcanised rubber provides comfort and durability. All these materials are available in 23mm lug width and suit the sport-oriented silhouette of the model.
How do you change the strap on the Citizen Eco-Drive BU2013-08E?
The strap is changed by extracting the spring bar terminals using a dedicated tool (spring bar tool) or a straightened pin. Position the tool in the small lateral slot of the terminal until it releases from the internal spring. Repeat on both sides and the strap will come free. For installation, seat the new strap in the lugs and reinsert the terminals, verifying proper engagement with a gentle pull.
Is the Citizen Eco-Drive BU2013-08E compatible with aftermarket straps?
Yes, thanks to the standard 23mm lug width, the BU2013-08E is fully compatible with many quality aftermarket straps. Always ensure lug width is precisely 23mm, as minor variations (22mm or 24mm) would compromise fit. Bespoke artisanal straps are recommended for those seeking quality and exclusivity.
How long does a leather strap last on the Citizen Eco-Drive BU2013-08E?
Leather strap lifespan depends on tanning method and usage: a quality vegetable-tanned leather strap, worn regularly but not daily, typically lasts between 3 and 5 years before replacement or restoration is needed. Factors such as humidity, frequency of water exposure, and routine care significantly influence longevity. The patina developed represents aesthetic value, not functional deterioration.
