Hello PuristS,
I have been lurking here for a while and meaning to get arround to posting an introductory post. I am from Melbourne Australia and my interest in watches is mostly focused on vintage Omegas but encompasses diverse other things as well. I have a small, humble collection that I hope to grow along a broad general theme.
I very much admire the depth of knowledge displayed here on PuristSPro and enjoy the different tone/culture here from that of other forums. While I remain active on other forums I hope that I can contribute when I have something to offer to the discourse here.
Here is my collection in overview:
with the exception of my latest arrival:
From left to right I have my everyday beater, a SMP300 ref 2531.80, a Railmaster XXL which is my one 'new' or 'current range' Omega, a cal. 911 flightmaster from 1971 and my newly acquired SM200 ref 166.091 also from 1971. I am particularly fascinated by Omega's pilot line models from the 1970's and would love to acquire more of these over time particularly a ref. 166.0093 and or a ref 176.004. This recent acquisition came with original box, instruction manual and purchase receipt. 
I think these two make a great pair. Here are the others in a little more detail. The Railmaster XXL, which many people feel is too big but I like just fine. When on occasion the topic of watch size comes up you can expect me to chime in with an impassioned defence of classically styled but contemporary sized watches:
And the business end of the Railmaster:
This is my Dad's 1966 Seamaster 30. It was a wedding present from my Mum to my Dad and I inherited it when he passed away. Probably one of the reasons I got into Omega's in particular when I developed an interest in watches.

I love the patina on the dial and even though it is GF not solid gold it is of huge sentimental value to me.
Here is my flighty. I don't know what it is about the cal. 911 flightmaster but it has just captured my attention ever since I got into watches. 
As you can probably see, I like my watches with a bit of 'wabi' or signs of use. I am fascinated by watches that were made for a utilitarian purpose but have ascended to a collectable status due to there inherent design quality. Yes it would have been easier to say "I like tool watches" but I think that is an often over and misused term.
Anyway it is good to finally be able post here and I look forward to contributing where I can.
Regards,
Zac
