Description

An all-Italian heart beats in this limited edition of 370 timepieces: OISA 1937 Caliber 29-50, Cinque Ponti manual mechanical movement.

The extremely flat movement contains 19 rubies and provides a very high frequency of 25,200 oscillations. This guarantees a long-lasting autonomy of about 60 hours. It has an anchor escapement and a variable inertia balance. 

The Perlage and Cotes de Geneve finishes are applied by hand in-house. The glass is subjected to a sapphire antiglare treatment and the case is made of AISI 316L steel and titanium, water resistant 10 ATM.

Mr Morezzi founded O.I.S.A. - Orologeria Italiana Società Azionaria – was founded in Milan by Mr Domenico Morezzi in 1937 , starting a handcrafted production of movements designed, machined and assembled in-house. OISA 1937 patented and marketed numerous brands of wristwatches.

O.I.S.A.  revealed remarkable production capacities for the technologies available at that time, producing 10,000 movements per month for a total of over four million watches sold and more than ten calibres developed in-house. OISA has always been a family-run company with around 120 employees led by Domenico Morezzi with the support of his grandson Carlo Boggio Ferraris. After his grandfather's death,  the nephew Carlo took over the company and guided it till 1978, when the arrival of quartz movements obliged many mechanical movements factories to close.  

Carlo Boggio Ferraris, together with Marco Mantovani, President of LOCMAN, Benedetto Perrotta of Officina Meccanica Futura, Fausto Berizzi as Industrial Director and a high-level financial partners, in 2020 decided to reopen the company and to create a very concrete industrial project.

Today, OISA 1937 is dedicated to manufacture  the high quality caliber 29-50 Cinque Ponti (five bridges), originally designed in the 1960s by Domenico Morezzi and now remodelled in terms of mechanics, aesthetics and materials.

The new caliber 29-50 was presented for first time to the press and to the market in Milan, in the old head quarter of OISA in Corso Como 10, together with the new LOCMAN MONTECRISTO watch on April 7, 2022.
