Strap for Max Bill Automatic Black Stick

The Junghans Max Bill 027/4701.00 features a lug width of 20 millimetres. This measurement represents the internal distance between the case lugs where the strap attaches. Verifying this dimension before purchasing a replacement strap is essential to ensure complete compatibility and proper fit.

For the Max Bill 027/4701.00, we recommend a strap in vegetable-tanned leather with dark brown or black finishing, which respects the minimalist Bauhaus aesthetic of the model. Alternatively, a grey or black NATO strap offers versatility whilst maintaining the conceptual simplicity of the watch. Your choice depends on intended use: leather for formal occasions, NATO for everyday wear.

To change the strap, obtain a spring bar tool or a sturdy toothpick. Locate the spring bars (the small metal pins supporting the lugs), press towards the centre of the case to release the spring, and slide the strap out. Repeat on the other side, then insert the new strap by aligning the holes with the spring bar ends.

Yes, provided the strap is compatible with the 20-millimetre lug width. High-quality aftermarket straps often offer superior materials compared to the original, allowing you to personalise your watch's appearance whilst maintaining technical and aesthetic compatibility.

Leather strap longevity depends on usage and maintenance. A quality leather strap with vegetable tanning can last 2-4 years with daily wear. Natural ageing imparts patina and character. Periodic replacement is normal and allows experimentation with different materials and colours without compromising your timepiece.
