4-6 weeks to do a battery change! And £290. Wow. Is there anything special about doing this? If it was me I would do it myself or go elsewhere - just checked, apart from the hassle of screws holding the caseback on it is easy. Someone in 2017 got the job done at omega boutique and it took a week and cost $60 including a nice service pouch on return. Last year omega charged £183 but they got new hands, crown along with case & bracelet refinished. I would go back to omega for more clarification on the work done.
