Vintage Longines UltraChron, 1970’s

Beautiful vintage Longines UltraChron. I bought it through the Vinted Authentification service a while ago so feel free to do the same, or feel free to trust me, it’s up to you! Offers accepted. For full transparency, the date function doesn’t work, so it’s stuck on 24. However, it keeps exceptional time. The movement does knock around a little bit but in all honestly, although this runs well, it could do with being looked at by a watchmaker. Strap isn’t original, 18mm lug width. Serial number on the case back is faint but it reads 15979934. Any questions please don’t hesitate to ask. Only selling as I prefer a slightly different case shape and I have quite a rugged job so don’t get a chance to wear vintage very often! No box or papers, just comes as it is.
