Heuer Montreal Lug holes

Hi,
Could anyone enlighten me regarding how close the lug holes on a Heuer Montreal are to the edge of the case.
I recently bought one and have had it serviced but my Watchmaker said I ought to keep an eye on the holes and maybe possibly fixing the spring bars permanently.
After looking at many images of Montreal's on the internet it seems as if it is just how the case was designed with the holes close to the edge of the case.

@Heuerfanboy Lug holes are indeed close to the edge.

Thank you for confirming what I thought,the holes on my Montreal are exactly the same.
