Strap for Chronoris Date / Movember / Bracelet

The lug width (ansa width) of the Chronoris 01 733 7737 4034-Set MB is 19 millimetres. This dimension is measured between the two spring bar pins that connect the case to the strap: it is the fundamental parameter for selecting compatible aftermarket straps. An incorrect measurement compromises both fitment and overall aesthetics.

For the 39mm Chronoris, we recommend a textured alligator in black or dark brown for formal-sporting use, or vegetable-tanned calf leather in tobacco tones for those who appreciate natural patina development over time. For more dynamic environments, a military-spec NATO in grey or maritime blue amplifies the instrumental character, whilst FKM rubber is ideal when versatility takes precedence over formal elegance. Your choice should reflect intended use frequency and professional context.

Obtain a dual-prong spring bar removal tool. Position the watch on a soft surface to protect the case. Insert one prong of the tool under the spring bar pin from the opposite side of the lug, lifting gently until the pin disengages from its seat. Repeat for both pins. Insert the pins into the new 19mm strap following the reverse process. Verify that both pins are fully seated and the strap has no play against the lugs.

Yes. The Chronoris features a standard 19-millimetre lug width, widely available in the quality aftermarket strap sector. On milanostraps.it you will find a dedicated collection of 19mm straps in leather (alligator, calf, shell cordovan), NATO and rubber—all hand-crafted and ready for dispatch. Compatibility is guaranteed, though always verify the lug width specification before purchase.

A quality leather strap (alligatore, vegetable-tanned calf, shell cordovan) typically lasts between 3 and 7 years, depending on intensity of use, climate and maintenance. Continuous exposure to moisture and temperature fluctuations accelerates degradation. Vegetable-tanned leather develops a natural patina that extends its aesthetic life considerably. To prolong durability, avoid prolonged water exposure and store the watch in humidity-controlled conditions.
