No, I don't believe OP expressly and openly encourages its customers to change straps frequently, but neither does SWATCH (not the group but the plastic watch). Having said that, like SWATCH, Panerai sells a large range of straps with lots of different shades and colours (including the less conventional colous). For those who have not checked, just go to OP's official web site, go to accessories. Out pop a long list of strap/watch measurement, each item on the list will in turn contain a sublist of straps.
Not unlike Ulysses having to navigate between the Scylla and Charybdis, I'll (wisely) keep my comments to what's factual and empirical above - members can draw their own conclusion what this means as regards strapchanging & the temptation to change straps and how this ultimately reflect upon the brand.
I do not deny the fact that the list is extensive and the colours varied, but to make thing clear, least we come to the wrong conclusion:
1. The fact that most Panerai watches comes with 2 straps, usually one leather and the other rubber or velcro or coramid straps.
2. Panerai does have watches in the following sizes: 40, 42, 44, 45, 47 and larger sizes and these watches comes with different size straps and even between models, different colour straps or material.
3. Leather, rubber, cloth and velcro do not last as long as metal bracelets. Just to highlight, I myself have gone through 3 sets of straps on one of my watches as I use it almost daily.
Yes, some of the colours are a 'tad bright' but they are there to facilitate those who are more fashion conscious amongst us and also for the fairer sex who may not want the typical boring black strap.
And to answer you question Peter:
1 - When did the PAMs started to come with the tools to change straps?
Since 1997/1998 when Panerai watches were sold to the general public.
2 - So were the brand "encouraging" the users to change straps?
Actually no. In the early days, Panerai actually prevented independent strap makers from using their watches to showcase these independent straps. However, along the way, they realised that this trend of changing straps would not stop, so I guess they took the decision to join the band wagon and make some money from this trend. However, I don't think this is really a big business for Panerai as from what you can see, there are hardly any Panerai collectors that will post pictures of their latest Panerai straps favouring the independents. Additionally, if you go to the boutiques or even the Ad, you will be hard pressed to see the entire collection of Panerai straps. Most of the time you would have to order the straps.
