Strap for Submariner Date 16613 Black Superluminova

The lug width of the Rolex Submariner 16613 Black Superluminova is 20 millimetres. This dimension is measured between the spring bar pins (from the inner edge of the left lug to the inner edge of the right lug) and determines the compatibility of any replacement strap. Verify the measurement using a digital calliper inserted between the pins to ensure exact correspondence before ordering a replacement strap.

For the Submariner 16613 Black Superluminova, straps in alligator (especially in brown, cognac or black tones), shell cordovan (burgundy or black), vegetable-tanned leather, or sports-oriented rubber Tropic straps are recommended. Alligator represents the predominant aesthetic choice because its natural grain enhances the bi-material casing in yellow gold and stainless steel.

Strap replacement requires the use of a specialised tool (spring bar tool) to gently remove the elastic pins from the lugs. Position the watch on a stable, padded surface, gently lift the pin from its seat using the tool, extract it completely, then insert the new strap and re-engage the pin in its respective seat until a click confirms secure fastening. We recommend carrying out this operation with care to avoid scratching the case.

The Submariner 16613 Black Superluminova, with its 20 millimetre lug width, is compatible with any strap manufactured for 20 mm lugs. However, to preserve the aesthetic and functionality of the model, we recommend selecting straps designed for professional diving instruments, such as those in alligator, cordovan or rubber, rather than lightweight dress straps.

The durability of a leather strap depends on the quality of construction, the material chosen and the conditions of use. An alligator or shell cordovan strap of artisanal quality maintains structural integrity for between 3 and 5 years of regular wear, developing a characteristic patina. Vegetable-tanned leather tends to show wear more visibly but in a controlled manner. Rubber Tropic straps have greater durability (5-7 years) due to resistance to UV rays and humidity.
