The Sinn U1 has been very popular, notably in Singapore with retailer The Hour Glass commissioning several exclusive limited editions, of which several forum members own (I own the U1 Tempus, shown below).

The latest diver's watch from Sinn is the 47 mm Ultimate U. Like the rest of the U series it is made from submarine steel and features a Tegiment hardened bezel.
It is exclusive to The Hour Glass and only 200 will be made.

Press release:
15 November 2009, Singapore – The Sinn signature U series like you’ve never seen before. Bigger, bolder, un-missable - The Hour Glass is honored to present the world premiere of the largest ever watch made by Sinn, created exclusively for The Hour Glass. Aptly named the “Ultimate U ”, its grander size is encased in an imposing un-missable 47mm case, crafted from the same German U-boat submarine steel from which it derives its name. Following hot on the heels of two prior limited-editions for The Hour Glass – the “U Black” and the “Tempus U1”, the U Series legacy continues with the “Ultimate U ”. Limited to only 200 pieces in total worldwide production.
The ‘U Series’ Legacy Continues
The background and exceptionally sturdy case of the German submarine steel, unparalleled in its remarkable resistance to seawater and anti-magnetic quality, sets the inspiration and creation of the U Series. Exclusively for Sinn, the steel supplier of Howaldtswerke-Deutsche Werft and Nordseewerke Emden GmbH shipyards are supplying the watchmaker with smaller amounts of exactly the same steel of which the world’s most modern non-nuclear submarines are made – the new submarine class 212 of the German Navy. A technical marvel of unparalleled reliability, it can be tegimented especially well. The rotating bezel’s minute scale for dive time reading is milled directly into the steel to assure safety, illegibility and accuracy. Tested by Germanischer Lloyd, the global authority in pressure testing of submarines, the Sinn U Series is the ultimate indispensable equipment for professionals and sports divers.
With key distinction in its new oversized case, with a larger crown, the “Ultimate U ” has a special dial embossed with the outline of a submarine. Its date marker on the dial presents the 30th day in each month in white, as a distinction to The Hour Glass’ 30th anniversary this year. Its caseback is engraved with “The Hour Glass Limited 200”. Each watch is also accompanied by a certificate that is personally signed-off by Mr Lothar Schmidt, CEO of Sinn.
The Sinn “Ultimate U ” is exclusively available at The Hour Glass.

U-Bill ah nice sound to it. How many should there be in this edition?
I actually have the white face U1 on order not sure when it arrives.
I will have to take a few snaps of the U1 family.
HAGWE
are there any wrist shots or pics next to a U1 for comparison..??
Is Bill the Sinn ambassador...LOL...as I'm sure this will soon grace his wrist..!!
Yours,
Andy.
PS - will that leather strap fit a U1..?? It looks like a beauty..
although the perspective doesn't show the difference very well, it is noticeably larger than the original, though not extremely large. The new crown is enormous so the watch still retains good proportions although the date is a bit small.

yes it does look nicely proportioned...and love the leather strap.
Andy.
...but from a slightly different angle. I don't mind this U1 (if only their press agent was actually aware that the submarine profile on the dial is a 212, instead of just "a submarine"...but I digress).
I agree on the LE and pushing of the 'collector' status.
The angle I come from is not buying any more divers UNLESS I can dive with them. Vintage only, too...
The press release I posted reads: "Exclusively for Sinn, the steel supplier of Howaldtswerke-Deutsche Werft and Nordseewerke Emden GmbH shipyards are supplying the watchmaker with smaller amounts of exactly the same steel of which the world’s most modern non-nuclear submarines are made – the new submarine class 212 of the German Navy."

I really like Sinn products. I have a thing for the U2 in particular.
I did see that they mentioned the 212 (not sure what's scarier being in a fuel cell sub or a nuclear powered sub!) in relation to the case material, but the rest of the press release just calls it "a submarine". That's all.
It's just too bad that at 47mm, the watch is just too big for my relatively slim wrists though
GREAT looking Sinn.. i really like it a lot untill i found out about the Price !!!!
for 5,200 US $ ?!!!! i'm gonna pass.
THANKS FOR THE INFOS.
