Initially I was and is still thinking to focus on a single brand, not Panerais but Rolexes because I believe they cover almost if not all permutations in horology that I like. I have no interest in perpetuals, tourbillion, haute complication pieces anyway.
But every time I take a peek at the Chopard LUCs, UN Marines, AP ROs.. my heart skips a few beats. They offer such great deals and bargain in the preowned market. The finish, fit and passion that goes into it is quite unparalleled. Robust calibres for everyday practical use.
All I mean is that the road is long and the temptations a aplenty. To stay true is hard and all the best to your direction 
Anyway, having owned and is still owning one Pam, I am not impressed with the price, build and the offer that it is giving. Panerais is not discreet and its the opposite. But who am I to question passion? Omega's new 8500 PO is by far a better watch than the previous model Sub, but yet I would rather live with a Sub. To each their own I guess.
I always do wonder, do u get cheaper ebauches if u order a 7750 without the chrono modules?

It was also in my mind to swing and make Rolex the core of my collection. Saying that I don't really like the cyclops on the Rolex. That in itself has limited the selection available to me, with the likes of the Submariner, DeepSea SeaDweller, Milgauss and Daytona. I already have the SeaDweller and the GMT Master and the DSSD does not do it for me neither does the Milgauss nor does the Daytona.
As for my future direction and future temptations, I have to say that I will stay fast and steady. Even collecting Panerai will come to an end soon. I am looking at a Destro and a base and maybe a logo. The PAM00219 answers the Destro and base need. The logo? Maybe yes maybe no as I am not really into the logo. We will have to see.
I have been shown a number of interesting pieces at very interesting prices (by my so call friends, with them you don't need enemies), but the watches did not hold any interest. Even the recent trip to HK did not spark any interest. I actually walked past Heritage 1881 without visiting any of the watch shops there. Same along Nathan Road. The only shop I did actually stop was the Panerai Boutique at Canton Road and that caused a huge dent in the wallet.....
I have been 'collecting' watches for about 20 years now and I think the interest may not be as strong now as it was before. I still do buy and subscribe to watch magazines (in English, Japanese and Chinese, but can only read English), I still do read books on watches, having just picked up the latest edition of the book 'Wristwatches' by Gisbert L. Brunner and Christian Pfeiffer-Belli. I still write my blog. I still visit watch forums (actually MWF and MWR are the only two I visit nowadays).
Yes there are a number of pieces I would still like to get, but at the same time, I don't seem to be able to justify getting them. I would still want to get an Omega Moon watch, I would still like to get a German watch (with a German made movement) and I would still like to get an AP Royal Oak Chrono (none of the ROO stuff). But as time (pun not intended) goes by, the need seems to dwindle.
