Strap for Senator Diary Stainless Steel Bracelet / Black / Bracelet

The lug width of the Glashütte Original Senator 100-13-02-02-14 is 20mm. This measurement represents the net distance between the spring bar attachment points and determines compatibility with aftermarket straps. Verify the width with a digital calliper, positioning the instrument at the base of the lugs to ensure correct installation.

For this timepiece, alligator leather represents the finest choice, as its natural grain harmonises with the satin-finished steel case surfaces. Alternatively, vegetable-tanned calf leather offers a more informal character with chromatic evolution over time. NATO straps in jacquard fabric provide durability for sporting contexts, whilst fluoroelastomer rubber ensures weather resistance whilst maintaining formal elegance.

Strap replacement is performed by extracting the spring bar pins using a dedicated tool (spring bar tool). Position the pointed end beneath the pin, apply gentle pressure to compress the internal spring and slide the pin from its seat. Repeat the operation on the opposite side. Insert the new pins ensuring they enter correctly into the case holes. We recommend consulting a specialist technician to avoid scratching the case.

Yes, it is possible to install superior quality aftermarket straps whilst strictly respecting the 20mm lug width. Ensure that the chosen strap has been manufactured with precise construction tolerances. At Milano Straps you will find a selection of straps in alligator, vegetable-tanned calf, NATO and rubber, specifically compatible with this lug width, ready for shipment and customisable according to your chromatic preferences.

Durability depends on frequency of use, climatic conditions and material quality. An alligator strap with vegetable tanning, subjected to regular maintenance (periodic cleaning and treatment with specific protective creams), can last 3-5 years of daily use. Vegetable-tanned calf leather typically offers similar longevity. NATO straps in jacquard fabric and fluoroelastomer rubber provide greater durability, up to 5-7 years, as they do not suffer the effects of environmental factors such as humidity and temperature fluctuations that characterise natural leather fibres.
