The Benrus DTU-2A/P is a 'front-loader' with split stem to allow removal of the movement through the front of the watch, with an inner stem locked into the movement and the outer stem with crown attached, fitting through the stem tube and clicking onto the inner stem.
The split stem arrangement is a weak point in the design, and when the click-joint between the inner and outer stem wears or corrodes, the outer stem can unintentionally separate from the inner stem resulting in the loss of the outer stem and crown.
As a result over the years, many DTUs have lost their original crowns, which are either missing or have been replaced with crowns of a different design.
The original crowns are almost impossible to source, so we have had crowns remanufactured in Switzerland, using an original 1965 Benrus DTU crown as the pattern. The crowns are excellent quality stainless steel with inner gasket, made to the same dimensions and specification as the original crowns.
These crowns are the closest available replacement for the original crowns and nobody else had these crowns - you can only get them here!
The crown was made specifically for the Benrus DTU-2A/P but is also suitable for use with the Benrus GG-W-113 which is the same design and suffers from the same split-stem issues.
The crown is also a suitable substitute/replacement from the Hamilton GG-W-113, but will require a female outer stem. The crown will also fit the plastic case Benrus Mil-W-46374, although the crown is slightly less deep than the original crowns for these watches.
Some crowns originally fitted to DTU-2A/P had a 'dimple' marked on them - a short, straight line stamped into the outside of the crown, which indicates the orientation of the outer stem, so it could be lined up with the inner stem more easily when being fitted.
Not all watches had this dimple, and the crown are supplied without the dimple, but if you want a dimple on your crown then we can add that for you. You just need to message us to ask before the item is packed and despatched.
Examples of crowns with dimple are shown in the images.
The threaded tube for the outer stem is Tap 10 (1.00MM) and we are able to supply outer stems of the correct tap size, with either a male or female fitting. The original inner stem for the DTU has a female fitting, so the correct outer stem required is a male fitting. However, some watches have had different inner stems substituted, where a female outer stem may be required.
