Vaughan’s Big Date — Eterna

The Swiss watch­maker Eterna Vaughan’s Big Date launches, with a new mechan­i­cal move­ment, cal­iber Eterna which is one of the thinnest in its class and allows the dis­play of a great date.

Eterna Vaughan’s Big Date

In the field of horol­ogy, the term “big date” when the date is indi­cated by large num­bers on two sep­a­rate disks: one for units and one for the tens. The imple­men­ta­tion of these two discs allows the use of larger num­bers for bet­ter read­abil­ity of the date. With auto­matic mechan­i­cal move­ment Eterna, an exter­nal drive dis­plays the num­ber of units for the days of the month while a smaller and slightly off­set inward scrolls four dig­its required for the tens disc. This tem­plate is domed on both sides, which gives it the shape of lens. Both discs large date blend per­fectly with the curved sur­face of the move­ment. They are not formed, as is usu­ally the case, two flat discs hor­i­zon­tally stacked, but two con­vex rings rotat­ing one beside the other.

Vaughan’s Big Date has a cal­en­dar fast date cor­rec­tion. At mid­night he updates in less than a sec­ond. Unlike most tra­di­tional watch move­ments, the mech­a­nism allows the manip­u­la­tion of the watch and the cal­en­dar for 24 hours. Pulses for rota­tion of the tens wheel are trans­mit­ted directly from the disk units of the big date. To ensure the low height of the move­ment, the tech­ni­cians have devel­oped an Eterna date disc with ball bear­ings and inte­grated mea­sure­ment. Man­ual cor­rec­tion of the date occurs, as usual, using the crown. A 360 ° rota­tion leads to cor­rec­tion of the date two days.

This new move­ment is inspired by Eterna cal­iber 1504 dat­ing six­ties. How­ever, its design­ers have sig­nif­i­cantly mod­i­fied the orig­i­nal. Ease of main­te­nance and longevity of the move­ment were opti­mized. 3030 cal­iber dis­as­sem­bled com­pletely, thus offer­ing the pos­si­bil­ity to replace any part. The cen­tral com­po­nents of man­u­fac­ture use a pho­tolith­o­graphic method. This allows devel­op­ing with extreme pre­ci­sion, com­plex minia­ture ele­ments, often pro­vid­ing vital func­tions of the watch move­ment. It pro­vides nickel alloys or nickel-phosphorus vir­tu­ally inde­struc­tible thanks to their extra­or­di­nary hard­ness.  High tech­nol­ogy rubs here artis­tic metal work, with a long tra­di­tion in watch­mak­ing. Bridges of Eterna cal­iber 3030 are rhodium-plated and dec­o­rated with “bead­ing” and “stair­case”. The oscil­lat­ing weight is dec­o­rated so like Côtes de Genève.

The shape of the lens move­ment, always rounded anthracite and pol­ished Stain­less steel case dial gives this Vaugham a sober and ele­gant look.
