By TLex About 10 years ago Schaumburg Watch presented the Aquamatic 1, which by all accounts was a very successful release. The case used for the AQ 1 was shared by a number of boutique and private labels. For my knowledge Schaumburg Watch was the first to come out with the design.
The AQ 2 was one of those legendary 2000 meter factory case divers that was used by absolutely everybody under the sun, and is still is by one or two, today. The AQ 3 was an unremarkable internal bezel diver sharing its case with one of the (now defunct) San Antonio Watch Co. divers.
This is the fourth generation of the Aquamatic, as previous generations it is equipped with all the requirements needed for a professional divers watch, so what’s new? Well, everything basically, but more interestingly; it would appear that for the first time, the Aquamatic’s case is unique. It has one or two interesting features, too.
The lugs of the AQ 4 have been hollowed out on the sides. They appear to be detachable from the case. The crown guard, which has a similar design has an unusual configuration with only one side protecting the crown. I wonder how functional that is?
The AQ 4's matt steel case is fitted with a divers bezel with some nice coin edging and a wave pattern on its top side, that is reminiscent of a UN diver. Its 12hr pip is made out of Ceranova (Ceramic Superluminova). The 45mm x 14 mm case can withstand pressure up to 800 meters.
However Schaumburg Watch certified the case with only 500 meters. Before delivery each case is tested up to 80 bar in-house. Further features include an AR-coated Sapphire crystal and a solid steel caseback attached via six screws and engraved with the brand’s new logo.
There are four different dial options for the AQ 4; these are: a black full-lume dial that glows blue, an orange full-lume dial that glows yellow, a black carbon fiber dial and 2 3D dials, one in black and one in black with a wooden ring!
The AQ 4 is powered by an automatic, SW20A caliber (not sure what that’s based on, I believe SW stands for Schaumburg Watch not Sellita). It is supplied with an automatic watch winder as well as a handmade leather strap with an option for a steel bracelet.
