Introduction : The 1st time I saw this watch was from a Japanese version Omega magazine in 1995, this watch did not catch my eyes at the very beginning as the Seamaster 600 "ProPlof" did as the case design has not been very outstanding by looking from the front as shown above. Only until I purchased this watch (Mainly because of it's 1000 meters diving ability), I noticed that the case design is not actually that simple. It shows that it was well designed to meet the requirement of 1000m diving depth. The stainless steel mesh type bracelet which is being lock by a spring type flip lock also shows that it was well designed for diving purpose.

Descriptions : Huge (43mm across bezel, 55mm case including Lug-to-Lug). Stainless Steel 1000m diving watch with reversible quick-set date & rotating bezel. 

SEAMASTER Professional 1000m / 3000ft : Case Reference ST 166.0093. Introduced in Collection 1975 with Automatic calendar movement Caliber 1012 - mineral crystal - screwed crown. This sample comes with original mesh type bracelet. Spring lock buckle. Front access case. Rotating bezel.

 

Comparison between Model 600 & 1000 :   Compare to the  Seamaster 600 known as "ProPlof" diving watch shown on the photo. This Seamaster 1000m / 3300ft diving watch is a better waterproof / diving watch. As noticed has a waterproof / diving ability up to 1000m (approx 3300 feet) tested. Seamaster 1000M & 600M Even though the shape and design of this watch has not made it as popular as the ProPlof Seamaster, yet it is consider a very collectable Seamaster diving watch as I believe not many were made during the 70s.  It is one of the best diving watch that Omega has ever made.

Seamaster 1000M / 3300FT

THE DIAL :~ The dial of this watch is quite similar to the ProPlof Seamaster, except that at 6:00 position, it has written Seamaster 1000m / 3300ft Professional instead of Seamaster 600m / 2000ft Professional or the other type Seamaster 600 that I have seen. Dial has a mat blue finish for this one. Luminous hour markings, signed Omega Automatic at 12:00. Hour & Second hands are white and Minute hand is Orange in color. Date at 3:00. Also signed Swiss Made at the bottom of 6:00 position.

DIAL

Case Back Stainless Steel Bracelet & Buckle

Case Back : The case back of this watch as shown has a horizontal groove pattern which I think was designed to reduce actual contact area of the watch back with the human skin to avoid water being trapped. The Bracelet : This is one of the most interesting part of this watch which has been the MESH type stainless steel original Omega bracelet. I have previously seen this type of bracelet being sold with a Seamaster 600 Proplof but I think this bracelet was only designed for this 1000m diving watch because when I tried to put this bracelet onto my own ProPlof, I noticed that it was not tight fitted. This mesh type bracelet is quite heavy and it is being buckle up by a spring type flip lock (As Shown). It has a extension piece for length adjustment. The buckle is signed.

DESEMBLING :~ The picture shown on the right shows the major parts of which the watch is made out of. It has 2 x Rubber Sealing Rings (one for holding the movement & the base case and one for putting in between the 2 plastic seals), 2 x Plastic Sealing Rings (This assemble is to be placed in between the dial and the crystal for sealing), 1 x Spring Type Crown with Stem (This has double seals inside the screw crown for performing it's best waterproof function), 1 x Metal Screw On Locking Ring (This is to press and secure the crystal on top of the plastic sealing rings set in order to stop water from entering into the movement compartment), 1 x Thick Glass Crystal, 1 x Movement & Dial Set, 1 x Rotating Bezel (Snap On Type), 1 x Base Case & Bracelet.

Remarks : There is one thing that I would like to mentioned regarding this Seamaster 1000M & Seamaster 600M (Plorpof). I have noticed that often collectors will particularly specify whether that want to buy a so call right hand version & left hand version. From my point of view the dial on these watches can be rotated in order to switch in between left / right hand version. The reason why I say that is because this watch as shown is in right hand version but after I had it serviced last year and the repairer accidentally put the dial back and made it now a left hand version (Note : The watch is still using the same original movement).
