Raymond Weil RW3281

The RW3281 is an automatic movement manufactured by Raymond Weil. Based on the Sellita SW381-1, it operates at 28800 vibrations per hour with 25 jewels and features a moon phase calendar with date display. This caliber belongs to the RW Sellita-Based family, indicating it is not in-house but rather a customized version of an established ebauche. The movement remains in production and is used in Raymond Weil's collections featuring moon phase complications.
