Looks like we had the same taste back in 1990's...... 
Well I've long outgrown the watch as its way too small for my fat & bloated wrist now.
Tried to sell it but at the prices offered vs the current ORIS alarms, felt that it was more logical to just let my missus use it, to rotate as a daily office watch.
In total I purchased 3 Oris watches whilst in Singapore. The first was in 1990when I just got into university. It was a central sweep automatic with plexi-glass and a see through case back. Rare feature at that time. Less than S$ 200 maybe.
I was really taken in by the Oris slogan in the early 1990's ==> Its' High Mech. THere was this cool advertisment in black and white showing the mechanism of a wrist alarm and someone winding it I remember. That spurred me to save up and bought the wrist alarm in 1992. I was taking part time art lessons at Mount Sophia and I walked over to Penang Road after lessons one saturday afternoon to purchase the watch. S$ 450. I think.
My third and last Oris had a small subdial for the second hand, at the 9 o'clock position. 27J, anti shock, anti-magnetic. Paid a whopping S$ 630 for it. Got it at a shop near the Bugis MRT station, 1994 about the time of my graduation. I remember the leather gave way after only a few weeks, and I had to go to Oris' service centre somewhere between Outram Park and Tiong Bharu where I asked for a SS bracelet. This watch served me for a good number of years, travelling to wherever I travelled those days. I was not aware of being able to polish plexiglass those days, and its plexiglass was so scratched after a few years I decided not to wear it any more.
