Lug width to be confirmed

On this Hamilton Boulton H13421811 the lug width doesn't convince me, and I don't want to give you a number I'm not sure about. Write to me on WhatsApp with the reference or a photo of the watch: I'll check it and tell you myself.

Frequently asked questions

How do I change the strap on my Hamilton Boulton H13421811?

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.

How long does a leather strap last on a watch like the Hamilton Boulton H13421811?

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.
