Strap for Promaster Aqualand 200M Depth Meter

The Citizen ProMaster BN2029-01E features a lug width of 27mm. This measurement, taken between the axes of the two spring bar pins, is the standard for this dive watch model and determines compatibility with aftermarket straps. To verify the measurement with precision, use a ruler or digital calliper positioned perpendicularly between the two lug ends.

For the BN2029-01E, we recommend a vegetable-tanned leather strap (alligator or calf) for formal contexts, maintaining the breathability of natural leather. In aquatic environments or humid climates, a ripstop nylon NATO or FKM rubber strap ensures complete waterproofing. A shell cordovan strap elevates the aesthetic profile, developing a unique patina over time.

To change the strap on the BN2029-01E, you will need a spring bar tool. Position the watch on a soft surface, insert the flat lever of the tool between the lug and the original strap, then press gently downwards to release the elastic pin. Repeat the operation on the other side, then insert the new 27mm strap and secure the pins by pressing until you hear a click.

Yes, all straps with a 27mm lug width are compatible with the Citizen ProMaster BN2029-01E. MilanoStraps offers a complete collection of 27mm straps in various finishes: vegetable leather, alligator, shell cordovan, NATO and technical rubber. Always verify the lug width before purchasing to avoid incompatibility.

The durability of a leather strap depends on the tanning method used and the environmental use. A vegetable-tanned leather strap typically lasts 2-3 years with daily use in dry environments, developing a characteristic patina. Vegetable tanning, unlike chrome tanning, is more resistant to moisture but requires occasional treatment with natural wax. In frequently aquatic environments, we recommend rubber or NATO straps to preserve the leather over time.
