Clementkc's experience with his A. Lange & Söhne 1815 Up/Down highlights a critical, yet often overlooked, aspect of watch ownership: the potential for strap and spring bar choices to impact the integrity of precious metal cases. His detailed observations and accompanying images sparked a vital community discussion on lug hole wear, particularly concerning the use of aftermarket quick-release spring bars versus factory-supplied components. This article synthesizes the collective wisdom of WatchProSite members, offering insights into preventing and addressing such wear on luxury timepieces.

I picked up my 1815 updown around 6 months ago and I have been loving it. I’ve put it on both a delugs strap with the quick release and also a Camille Fournet strap. They both don’t have white gold spring bars but steel. I was taking a look today and it seems like the side of the strap without the quick release is being pushed into the lug holes and it’s polishing the white gold away? It’s the same on the 4 lugs. the quick release side looks fine but the other side I can see what looks like a sleeve Insert and like a rough pattern around the hole.

The hole away from the quick release.




The hole with the quick release.

Can this be fixed during service and should I maybe just move back to the regular strap and spring bars? Thanks!

About the A. Lange and Söhne Emil Lange Ref. 1815

The A. Lange & Söhne 1815 reference 206.032, introduced in 1999, is a notable example of the brand's commitment to traditional watchmaking principles. This model is part of the 1815 collection, which pays homage to the birth year of Ferdinand Adolph Lange and emphasizes classic design elements such as Arabic numerals and blued hands, drawing inspiration from historical Lange pocket watches. It represents a more understated and purist aesthetic compared to some of the brand's more complex offerings, focusing on fundamental horological excellence.

This particular reference features an 18k rose gold case measuring 36mm in diameter and 7.5mm in thickness. It houses the manually wound L941.1 caliber, visible through a sapphire crystal case back. The movement provides a power reserve of 45 hours. The watch is fitted with a sapphire crystal on the front, protecting a solid silver dial. Water resistance is rated at 30 meters, suitable for everyday wear but not for immersion.

The 1815 206.032 appeals to collectors who appreciate classical proportions and a focus on fundamental watchmaking without excessive complications. Its smaller case size reflects a more traditional approach to men's wristwatches, making it a desirable piece for those seeking a discreet yet highly refined timepiece. The combination of rose gold and a silver dial offers a warm and legible presentation, consistent with the collection's historical inspirations.

I’ve serviced hundreds of watches and have never seen wear like that except on old gold watches with bracelets that have spring-loaded expansion ends to fit various widths. Just because a quick release lets you change without tools doesn’t mean you should do it often. Is your quick release strap like the black one (form fit) or the brown one (straight end)? If the latter, whenever you wrap the strap around your wrist, the little pin you shove to release the strap forces the spring bar to rotate

I don't know if you're the one manipulating the spring bars or if someone else is. But whomever is doing it needs to be more careful to avoid scratching the inside of the lugs.

I don't know what kind of metal Lange uses for its springbars. Maybe they use a hard metal, maybe they use a soft metal. But if you can, try to use your Lange Spring Bars instead of the ones from Camille Fournet. If you can...

I have a Langematik in platinum, and when I looked at the lug holes it had an insert, I assume of a harder metal like stainless steel. The insert was on both sides. I tried a quick release spring bar from Delugs but quickly decided against it for a few reasons. First, the spring bar hole on Lange watches seems quite small, perhaps 1.5mm but definitely not 1.8mm. Second, there was a lot of resistance when turning the spring bar, so a lot of friction in the lug holes. Even with the Lange spring ba

A good lesson learned and luckily you caught it before it could become worse. Thankfully Lange is a brand that could laser weld metal back into your case to restore it as new when the time calls for it.

About the lever of the QR spring bar having an unintended consequence. I love changing straps and I love QR spring bars. I will keep this in consideration if I get a WG case. Luckily Pt is a little harder
