After a few days of enduring an Accutron 218 with an expansion bracelet that was about 2 links too short, and the resultant discomfort, I have decided to wear my one 50 year old Omega F300. This watch came to me, not running. Circuit and tuning fork seemed okay. It was bogged down with congealed oil, rendering it useless. So I cleaned it, and replaced the cracked crystal which cost me almost 4 x what I paid for the watch! But I ❤️ it!
