The Endurance U8777B-LA2.2, seen from the bench

The Limes Endurance U8777B-LA2.2 is a 41.20mm stainless steel chronometric instrument embodying Bauhaus rationalism in contemporary watchmaking. It houses a Sellita SW200-1 caliber with anchor escapement, date window, and central hours, minutes, and seconds display. The 22mm lug width is essential for proper strap compatibility and secure fitment without lateral play.

Frequently asked questions

What is the lug width of the Limes Endurance U8777B-LA2.2?

The lug width of the Limes Endurance U8777B-LA2.2 is 22 millimetres. This measurement is the essential technical parameter for identifying compatible straps. Measure the distance between the two lugs of the case using a digital calliper: a precision of 0.5mm is sufficient to verify compatibility.

Which strap is most suitable for the Limes Endurance U8777B-LA2.2?

We recommend an alligator or calf leather strap with vegetable tanning in cognac, brown or black tones. These materials amplify the minimalist Germanic aesthetic of the timepiece, developing a noble patina over time. For robust everyday use, a silk NATO or FKM rubber strap offers practicality without aesthetic compromise.

How do I change the strap on the Limes Endurance U8777B-LA2.2?

The Limes Endurance uses standard lugs with removable pins. Obtain a spring bar tool and position the watch on a soft surface. Gently extract the upper lug pin, slip off the old strap, align the new strap (22mm width) and reinsert the pin until it clicks. Repeat for the lower lug.

Can I use an aftermarket 22mm strap on this watch?

Yes, any strap with a 22mm lug width is compatible with the Limes Endurance U8777B-LA2.2. It is essential to verify that the width is precisely 22mm: a tolerance of ±0.3mm is acceptable, beyond which the fit would be imprecise. We recommend measuring the original strap with a calliper before purchasing.

How long does a leather strap last?

A quality vegetable-tanned leather strap, such as alligator or calf with vegetable tanning, has a lifespan of 3-5 years with daily wear. Longevity depends on ambient humidity, direct sun exposure and maintenance. Periodically treating with natural wax balm slows ageing, whilst prolonged water exposure accelerates fibre degradation.
