Strap for Boulton Quartz Small Second Stainless Steel / Silver

The lug width of the Hamilton Boulton H13421811 is 18.00mm. This dimension requires straps specifically constructed for this width, measured from inside to inside of the lug contacts. It is essential to verify this measurement before purchasing an aftermarket strap to avoid incompatibility issues.

For the Boulton H13421811, we recommend a strap in alligator leather with vegetable tanning in Cognac or Brown tones. The 18mm lug width creates ideal proportions with aged calfskin or heavy-canvas NATO straps as well. Selection depends on use: formal occasions require smooth leather, whilst casual wear benefits from NATO or rubber options.

Strap replacement on the H13421811 is performed via the through-bars (spring pins). Equip yourself with a dedicated tool (spring bar remover) to gently extract the bars from the non-lugged side. Align the new strap lugs with the case, then reinsert the bar until the locking click engages. Proceed with care to avoid scratching the stainless steel case.

Yes, any strap with a certified 18mm lug width is compatible with the H13421811. On milanostraps.it you will find a collection of artisanal straps specifically constructed for this width: Italian leather, NATO, and FKM rubber. All are ready for dispatch and customisable according to your aesthetic preferences.

Durability depends on daily use and the quality of the tanning process. A calfskin or alligator strap with vegetable tanning, worn 5-6 days per week, maintains structural integrity for 3-4 years. Ageing is part of its charm: patina increases aesthetic appeal. By rotating between multiple straps, durability extends considerably.
