I know this post is over a year old. But it is worth mentioning an alternative leather fitment is the leather “miracle braid” lanyard from @DaveK as shown on my Waltham Vanguard.
Unfortunately, no. I made an offer on the Vanguard I mentioned in a recent post before the estate dispersion sale, but I haven’t heard whether that watch was sold or not. Might hear after Xmas, but if not, I will enquire about it first chance I get. The one posted with your lanyard on it (above) has been shown here, before.
