The Single-Hand Watches PM901, seen from the bench

The MeisterSinger PM901 is a 40mm stainless steel watch with a manual-winding caliber and single hour hand, representing contemporary German watchmaking philosophy. It features a Sellita SW300-1 automatic movement with hours, minutes, seconds and date. The 20mm lug width is proportionally designed for this case diameter, accommodating strap thickness between 1.4 and 2.0mm. Part of the Single-Hand Watches collection, this model embodies essential watchmaking without visual excess.

Frequently asked questions

What is the lug width of the MeisterSinger Single-Hand Watches PM901?

The lug width of the PM901 is 20mm. This measurement represents the distance between the two suspension pins located at the case lugs. It is essential to respect this specification to ensure perfect strap fit without lateral play or excessive tension. An undersized strap would create gaps; an oversized strap would not fit into the pins at all.

Which strap is most suitable for the MeisterSinger Single-Hand Watches PM901?

The ideal strap depends on usage and personal preference. For formal elegance, we recommend alligator crocodile or shell cordovan with vegetable tanning, both developing natural patina over time. For daily versatility, Italian grained calf leather at 1.5mm thickness ensures comfort and resistance. For sports and informal occasions, a cotton-nylon NATO allows quick changes and practicality. FKM rubber remains the modern solution for those alternating between humid or athletic environments.

How do I change the strap on my MeisterSinger Single-Hand Watches PM901?

Strap replacement requires a precision spring bar tool. Position the watch on a stable surface and insert the flat tip of the spring bar tool into the small lateral hole located near one suspension pin, pushing gently inward to create leverage. The pin will slide out of the lug. Repeat for the second side. Insert the new strap by aligning the holes with the pin axes first, then reinserting the pins with uniform pressure until you hear a click. Verify that the strap is centred relative to the case.

Can I use an aftermarket strap compatible with the MeisterSinger Single-Hand Watches PM901?

Absolutely. Any strap with 20mm lug width is mechanically compatible. However, we recommend selecting straps with comparable build quality to the watch's value: minimum 1.4mm thickness, premium leather or certified technical synthetic materials, precise finishing in cuts and stitching. An economical, lower-quality strap does not compromise mechanics but reduces overall tactile experience.

What is the average lifespan of a leather strap for the MeisterSinger Single-Hand Watches PM901?

A premium leather strap, subject to moderate-to-intensive daily use, typically lasts 18 to 36 months. Cordovan resists longer due to structural density; alligator requires more careful maintenance to preserve surface crystals. Grained calf offers balance: typically 24-30 months of life before replacement is necessary. Determining factors include climate (humidity accelerates ageing), frequency of use, exposure to sweat, water, and detergents. Periodic maintenance—gentle cleaning and annual conditioning with natural wax—significantly extends longevity.
