Lange 1815 Pinkgold (2006 new acquisition)

Yes, Lange provides 金属链 for 1815.

The metal chain (either gold or PT) is quite expensive, I guess, costs several thousand euros.

My own preference is, however, leather watch strap for classic watches, since the watch appears more elegant on the leather strap than on a metal chain.

多谢版主回复，但我这是想给老爷子买的，老人家想要金链的，
不知道具体型号应如何表示

黄金皮带的是206.021那么金表带款是否206.321，

售价版主可否告知

You can mention gold chain when you order the watch. The dealer will take notes on your preference and make you an offer.

The gold chain costs several thousand dollars. The watch with leather strap costs 8800 Euro.

I guess the total price will be around 13000 Euro. Just a guess!
