Not an average Omega dresswatch! Why? Let's look! It has extremely big stainless steel case - 39 mm without crown in a very attractive "calatrava" design with thin flat bezel. Fantastic two-tone champagne dial has an unusual flat shape and offers everything you may ever want - charming tone, sector track and fantastic Roman ArtDeco numerals. In combination with fancy blue steel hands it reaches unbeatable level of elegance and attractiveness. It is powered by quite rare version of a well-known cal.30 which made Omega really famous - cal.30T1. Quite unique timepiece in outstanding condition.

Size guide for wristbands

1 | Lug width

The lug width is the width of the strap at the end that is attached to the watch. This is the interior distance between the two lugs (horn-like protrusions) on the watch casing. The strap will fit your watch only if the lug width of the watch is the same width as the strap.

2 | Buckle width

The buckle width is the width of the strap at the buckle end. If you want to keep your watch’s original buckle and replace only the strap, the width of the original buckle must be identical to the strap width. For watches with folding clasps, please choose a strap specially made for your particular clasp.

3 | Strap length

The strap length is the combined length of the short strap side 3A (without buckle) and the long strap side 3B. For metal straps, the length of the strap including the clasp is measured in the closed position.

4 | Strap thickness

Strap thickness is the height of the strap. Many leather straps thin out towards the buckle end, or “taper”. If you want to keep your watch’s original buckle and replace only the strap, the strap thickness must match the height of the original buckle. For watches with folding clasps, please choose a strap specially made for your particular clasp.
