Description Discover more
The Modello Tre ref. U3FB-AAS is a Made-in-Italy chrono-diver developed in partnership with Automobili Amos. It features a distinctive dust dial with two subdials and a fixed monoblock bezel engraved with a deep, acid-etched tachymeter for precise speed and timing measurement.
Timekeeping is handled by dust ladder phantom hour and minute hands filled with Super-LumiNova® GL dark orange, ensuring strong low-light visibility. The reversed lollipop seconds hand, finished with a safari-orange tip, matches the subdial hands for cohesive visual clarity. A 2.5 mm double-domed sapphire crystal with anti-reflective coating guarantees optimal readability in any lighting environment.
The watch is engineered with a solid 316 stainless steel case, sandblasted for a uniform matte finish, paired with a screwed-in caseback, an oversized 8 mm crown, and durable 5.5 mm screw-in pushers. Together with high-grade gaskets, these components ensure water resistance tested individually to 30 ATM (300 m / 1,000 ft).
Inside, the VK64 meca-quartz movement operates at 32,768 Hz for reliable accuracy and a 3-year battery life. The chronograph offers 1/5-second precision and a 60-minute totalizer. The timepiece is fitted with a dust TPU two-piece quick-release strap with sandblasted hardware signed UNIMATIC.
The screwed-down caseback showcases the “AA steering wheel” engraving and an individual progressive serial number. Each watch is covered by a 24-month worldwide warranty and belongs to a limited edition of 150 pieces.

FAQ Frequently Asked Questions
How to use the Modello Tre chronograph function?
UNIMATIC’s Modello Tre is a mecha-quartz chronograph, offering a 300-meter water resistance.
To use your watch’s chronograph function, unscrew the two pushers by rotating them downwards until they are all the way out; press the top pusher, in order to start the stopwatch, the second hand will start moving across the dial and the left minutes subdial will move accordingly.
Pressing the top pusher again will stop the chronograph and pressing it a third time, when the chronograph is stopped, will start it once again.
If you wish to reset your chronograph back to zero, simply press the bottom pusher, and the hands will immediately return to the starting position.
It is very important to remember to always screw down the pushers whenever you are not using the chronograph function, in order to help to maintain the proved water resistance. Please be aware that the second hand is dedicated to the chronograph function, it will not move if the chronograph function is not engaged.
What is a chronograph watch?
A chronograph is a timepiece that combines traditional timekeeping with a precision stopwatch function.
Its integrated mechanism enables the accurate measurement of elapsed time (60minutes).
By operating the pushers, you can start, stop, and reset the chronograph seconds hand with ease.
Why is every UNIMATIC watch individually numbered?
Each piece is produced in a strictly limited edition and numbered by hand on the caseback, guaranteeing its authenticity and its place within the series.
How durable are UNIMATIC watches for daily wear?
The 316L stainless steel case, double-domed sapphire crystal with anti-reflective coating and 360° protection system are engineered to take daily knocks in stride, from the desk to the water.
Are UNIMATIC watches water resistant?
All UNIMATIC cases are engineered to provide exceptional water resistance. Every UNIMATIC watch is individually tested to ensure a minimum water resistance of 300m (30 ATM), while selected on case modello 1 featuring our enhanced case construction are tested to withstand 600m (60 ATM).
Before exposing your watch to water, always make sure the crown and, where applicable, the pushers are fully screwed down and securely tightened. Never operate the crown or pushers while the watch is underwater.
After use in seawater, rinse the watch thoroughly with fresh water and dry it completely.Please refer to your specific model's technical specifications to confirm its certified water resistance rating.
What is a reference number?
A reference number is an alphanumeric code associated with each watch model (e.g., U1S-T-MP).
You can find the reference number in the documents provided at the time of purchase, such as the International Warranty certificate, or on the case-back of your watch.
Does the stainless steel bracelet fit my watch?
The UNIMATIC UBR-TLQ18 solid stainless steel bracelet is compatible with almost all the UNIMATIC lineup. Above is a chart to help you choose the correct end-link variation for your watch. Please note that the bracelet is available in two different finishes: Brushed and Sandblasted. While a bracelet may be mechanically compatible with your watch in terms of fit and attachment, it may not match the watch aesthetically if the finish is different.
