We had a friend stay over for the weekend and after some clothes / shoes / bag shopping the conversation turned to watches and she admitted that this was an area she's been neglecting and that she actually should get herself a more proper watch. Picture me switching into overdrive - a lady in distress and all it would take to sort it is to find a suitable timepiece

That should be a walk in the park.
The hours afterwards were a very educational experience. And no watches were purchased...
But let me start at the beginning. And a disclaimer - I have rarely felt so unhelpful before (so all of this may be my fault).

From: History Link 101
So over lunch I tried to assess her needs and desires first. Relatively large, round case, should be single watch, so versatile. Maybe a steel / gold combo to make it more versatile in terms of matching it to most of the wardrobe. Seemed simple enough.
We then went to the first shop and the theory met reality. Most of the watches I suggested went straight out of the window as 'not it'. The sales assistant was capable in my opinion and knew what she was selling (good technical knowledge, too), and I personally would have felt well served. But for a lady it seemed that the primary advice was - add diamonds (and MoP, etc.). The friend was reduced to pointing at things and trying them out. But not finding anything that she really liked.
Tried out several ADs and a Boutique with similar results.
Finally after the shops were all closed we managed to find a couple of watches in shop windows that fit what she imagined. I have to say that after a whole afternoon of discussion and watch shopping I would not have known that these were the ones she'd want. And nor did any of the store personnel figure it out.
Long story short. Some points that I know in hindsight would have helped.
First of all not simply assuming that diamonds is all it takes. Several brands offer female watches without but these were often not stocked.
Secondly, figuring out which male or unisex models to offer. There were several that were applicable but while she would get all the female models shown, the male ones she would need to 'find' herself.
Third point - straps. There were several watches she'd have liked to have seen with different straps. None of which were stocked and as almost no watches have quick strap change options (and I do not mean cross drilled lugs), it would have been hard anyway. Rolex would have been a serious contender if they had some watches on straps instead of bracelets (as demonstrated by her interest in Cellini's after being shown then, albeit they were too large).
Fourth, more watches with a steel case and YG / RG indices and hands.
So again this simply a personal experience on a sample of one and maybe the situation was untypical.
What are your experiences?
Are we as Purists not always ideally suited to advise women (I suppose that female Purists are a minority here) or is it just me?

Or was I simply choosing the wrong ADs? Any brands that you know that have the female customer served better?
