It would be great find for any collector

Up for sale is a genuinely historic, exceptionally rare, and highly investment-grade piece of German horology - the legendary GUB Glashütte Caliber 28 "Q1" mechanical wristwatch. This iconic timepiece was produced in the early 1950s in Glashütte, Germany, representing the peak of high-end post-war craftsmanship.

The historical value of this watch cannot be overstated. Caliber 28 is the only wristwatch movement ever fully developed and manufactured by the prestigious house of A. Lange & Söhne before all independent watch facilities in Glashütte were forced to merge into the VEB GUB state enterprise in 1951. This specific piece features the famous Q1 (1st Quality) logo on the dial, which was awarded only to high-precision chronometer-grade movements that passed rigorous testing.

The watch features a professionally restored, newly replated classic case that looks like brand new, alongside an authentic dial showing an honest vintage patina, heat-blued hands, a sub-second dial, and a clear acrylic crystal. The manual-wind movement is a true horological masterpiece. It comes paired with a premium, brand-new 16mm RIOS1931 Art Manuel matte mahogany leather strap handcrafted in Germany, featuring a polished steel RIOS buckle. Fully serviced and running beautifully!

DEFECTS: Authentic natural vintage patina on the original dial, consistent with a well-preserved mid-century artifact. The case has been freshly replated and looks immaculate.

Dimensions of watches

The town of Glashütte in Saxony has been the undisputed heart of high-end German watchmaking since Ferdinand Adolph Lange established his workshop there in 1845. Following WWII and the subsequent restructuring under Soviet administration, independent horological firms in Glashütte were merged in 1951 into the state enterprise VEB Glashütter Uhrenbetriebe (GUB).

The Caliber 28 holds a legendary status as the only wristwatch movement entirely designed by A. Lange & Söhne right before the merger. Timepieces stamped with the "Q1" (Qualitätszeichen 1) mark represented the absolute peak of post-war German precision and craftsmanship, passing strict accuracy testing before leaving the factory.

All Antique and vintage watches are mechanical. Repairs require precision, so please handle this historical artifact with care.

• Vintage mechanical watches should not be beaten or dropped - shocks can damage the balance staff.
• Vintage watches are generally NOT waterproof. Protect your timekeeper from direct contact with water, heavy rain, or high humidity.
• If your watch becomes wet it should be dried off quickly. Carefully open all covers and use a hair drier to blow dry the movement, dial, covers, crown. This will reduce the amount of rust.
• If your watch becomes wet with any kind of salt water you should immediately immerse or spray your watch with fresh (no-salt) water to remove all the salt from the works before drying the watch completely. Any salt left in the watch will combine with moisture in the air to rust metal components of the movement, case etc.
• Winding any mechanical watch tight may break the mainspring. Stop winding as soon as you feel the natural resistance tightening up.
• When adjusting the hands of your watch, move them in a clockwise direction only to prevent stress on the gear train.
• If you must adjust counter-clockwise make it for small adjustments only (i.e. for minutes, NOT hours).
• Be careful and gentle when adjusting the movement speed (faster or slower). Don't make sharp movements, and don't touch other components in the movement especially the pendulum mechanism.
• Every 2-3 years it is recommended to service, clean, and oil vintage watches to keep them running accurately for decades to come.
• IF the watch is dirty - allow the watch to run down, don't wind it again until you have it serviced by a qualified watch repair expert. Dust will absorb and remove important lubricants and cause the movement pieces to wear down.
• To clean the case, dial and crystal you should use a cloth that does NOT leave fibers as these may get caught up in the movement. Check with your Watch repair expert to get an appropriate cloth.
• Keep your watch away from strong magnetic fields (large speakers, modern computers, magnets) since magnetic exposure can alter the balance spring performance.
• Most Cases and Covers are fine components and will not handle abuse well. The watch should not be shaken, beaten, or stressed.
• Vintage mechanical watches naturally experience a daily deviation error of up to a few minutes. An accuracy of +/- 3 to 5 minutes a day is considered excellent for a classic timepiece.
• Mechanical watch is not recommended to use for engage in extreme sports, and expose them to excessive vibration loads. Recoil force, which take on the clock, affect their reliability and precision. No matter how perfect was not anti-shock mechanism, there is always the chance of excessive load that details of the mechanism can not survive.
