Big Pilot Watches - The Steinhart Nav B-Uhr II 44 Reviewed by Adrian Ainsworth Movement

The Steinhart Nav. B-Uhr II 44mm Automatic comes with an ETA 2824-2 movement with hour, minute and centrally located second hands. Obviously the date function of the movement is not being used as the watch was designed to be as historically close to the original Beobachtungs- Uhrens as possible, which did not have any date function. The movement has 25 jewels and beats at 28,800BPH.

According to the Steinhart website, the power reserve of the watch is at 42 hours.

Movement type: ETA 2824-2 made in Switzerland Jewels: 25 jewels, 28,800 BPH Power Reserve: 42 hours Complications: Hour, Minutes, Seconds


The case of the Nav. B-Uhr II is made up of a solid piece of brushed stainless steel with a screw-in caseback. The bezel and the lugs seamlessly integrate to the rest of the case. The case of the original B-Uhrens is 55mm which the pilots wear over their thighs or arms. The diameter of this watch is down to a manageable 44mm and a height of

14.2mm, small enough to wear on the wrist but still lending some wrist presence to the wearer of the watch. The 22mm lug width is perfectly proportioned to the rest of the watch and the size allows for a lot of strap options for the Nav, B-Uhr II. The length of the watch is about 52.1mm, but since the lugs curve downwards and the caseback is flat and huge, the watch is able to sit comfortably on the wrist with almost no lug overhang.

The watch weighs in at 107g, but even so its not uncomfortable and because it sits flat on the wrist it doesn't move or swing about.

What I particularly like about the case is how the lugs elegantly protrude and arc from the case and I am amazed at the workmanship that was put into making the case!

The caseback is also made up of stainless steel and is of the screw- in type. Given that the movement of the watch is an ETA 2824, probably without too much customization and decoration, I don't mind that the watch has a solid caseback. It is actually a nice piece of work, as there is a sharp engraved image of a 1940s pilot with the Steinhart logo and the text "STEINHART Nav. B B- Uhr II" on top. Along the circumference of the caseback the text "SWISS MADE • STAINLESS STEEL • SAPPHIRE CRYSTAL • SWISS AUTOMATIC MOVT." is also engraved.

Apart from the text on the caseback, the only other marking on the watch is the production number, which can be found on the side of the case at the 6 o'clock position. The watch has a push-in grooved onion-shaped crown with a rather
