It would be great find for any collector

Up for sale is a genuinely beautiful, highly collectible, and historic example of Swiss engineering – a mid-century Certina mechanical wristwatch featuring the esteemed in-house Caliber 321 movement. Produced in Switzerland during the golden era of mechanical watchmaking, this timepiece is built to a superb standard of durability and style.

A standout feature of this specific model is its premium case construction. Beneath the outer case back, the watch retains its original protective inner dust cover, a feature used to guard the high-grade mechanical movement from magnetic fields, moisture, and debris. The inside of the outer case back is officially stamped with the Certina Swiss / Acier Inoxydable signature, while the exterior cleanly displays the reference number 81101 and the unique serial tracking number 3049845.

The watch displays an incredibly charming, untouched original dial with a stunning vintage speckle patina, golden hands, and an elegant sub-second register at 6 o'clock. It is equipped with a classic domed acrylic crystal and comes paired on a highly sought-after, period-correct Speidel USA expanding metal "twist" bracelet that fits comfortably on the wrist and looks fantastic. The hand-winding movement has been completely checked, serviced, and is running smoothly!

DEFECTS: Honest, time-earned wear and minor cosmetic scratches on the stainless steel case, dial surface, and case back, fully consistent with a 70-year-old historic timekeeper.

HISTORY & LORE

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.
