In 2015, Glashütte Original released the Senator Panorama Date Boutique Edition, available exclusively at boutiques. This special version is based on the regular Senator Panorama Date Moon Phase and features a sleek stainless steel case and a beautiful blue dial adorned with white Roman numerals and a railroad chapter ring. There are four available references, all equipped with an alligator strap. One has a pin buckle, another a folding clasp, a third a short folding clasp, and the last one comes with a stylish stainless steel bracelet.
