Thanks! You certainly have a tight Seiko/Orient collection there. That SD GMT is quite a watch, however, my fav is the Ananta Auto Chrono. If I had a bigger wrist, that would be the watch I would love to get. Seiko also uses that solid 8R28 in the limited edition Velatura released a while ago. I think they use it on in another watch (I think a japan-only one but it escapes me now.) That’s cool you owned the 7T32 calibre…I currently have the 7T59 calibre in the Sports 150 Series. Excellent watch and I’m still surprise I found because it’s a rarer one being made for only two years.
Now to answer your questions. Sorry, I am not familiar with the 4R35 movement. I think it is a new movement….I do know that the Prospex series is a japan-only collection that will continue to be unavailable in North America. I am, however, familiar with the 4R15 movement, which is found in watches in the Spirit collection. I would love to see the prospex watches because some of them come in a comfortable 37-38 mm dial size! I wouldn’t even mind seeing the quartz-movements here! Alas we can continue to dream
Secondly, the SARB is another collection that will only be available in places like Japan, Hong Kong, Taiwan, and I think in Thailand and Singapore. Those are one of my favourite automatics (along with the SVCS’s) before entering the 6S (usually found in the Phoenix series) 9S (only found in the GS collection) and 8L (found in Credor and Marine Master among others) high-end auto movements. The only two watches with the 6R15 movement that are offered in Canada are the SPB007 and the Discus Burger. The SPB007 is an automatic in the Premier collection and the Discus Burger was made for the 2008 Power Design Series. Unfortunately both are discontinued. I believe that there might be a great movement breakdown on this forum somewhere that I also benefited from.
And lastly, the Ananta watches you have mentioned will be coming out around fall (between September and November) to the Canadian Market. I have no definite date to pass along to you though.
All the best,
