Suggest decent gift ideas

So my partner’s birthday is next month and i wanted to gift him something really special but i couldn’t save up enough for that and now my budget is under **₹1000**.

I gifted him a shirt last month, i have gifted him perfumes, watches.
He bought a wallet recently so😭💔

If it helps then he is a navy cadet and he likes ships, ocean and whatever else related to this obviously 😭
I have made him many handwritten letters and diy things and i will write him a letter too but i want to gift him something more!

He also likes food and music.

I am really confused because i want him to feel special but don’t want him to think i am broke loserrr😭😭😭😭

He is turning 20 if it matters.
